Inexpensive, defective yet functional with a hiccup lol

Item was pretty much as described. Had some damage that looked cosmetic but once we installed a couple months later after renovating room we noticed it runs with a very noisy fan noise. We should have installed sooner, missed the return window. It appears to cool fine , it is winter lol, but runs noisy even on fan.  We will limp along till we replace.  Saved some money and got a inexpensive functional yet hiccup unit! LOL

The keyboard quit working on my Toshiba, so I ordered a replacement from Amazon, thinking I'd install it myself. Turned out this particular computer with number keys, has hidden screws attaching the keyboard, so I couldn't install it without special tools & knowledge. So I bit the bullet and called a repair guy. He was able to get it open and installed, but the connector was the problem, and he didn't have the ability to make it work.

After paying him for essentially doing nothing, I overcame being mad at myself for being cheap and not taking the computer someplace else in the beginning. Now I had $80 tied up and still a broken computer. I borrowed a Mac keyboard and mouse from my desktop, which actually worked, but made the laptop pretty clumsy to use.

Then I ordered this wireless keyboard with touchpad hoping it'd work. It does! I like a mouse better but the touchpad works fine. I can even set the computer on a table beside me, and watch movies on Netflix with just the keyboard closeby. I'm using it all the time now. Maybe some day I'll spend the bucks to fix the laptop, but this system is working fine for now.

Brought two... one perfect the other defective; typical quality control

Loved the design and how thin and light it is.  It performs amazingly well for the CPU in it on all fronts, including 1080p Youtube videos.  However, this unit didn't make it past 2 days before I found a quality control issue unfortunately.  The Micro-HDMI out the side did not work and after wiggling ever so slightly I was able to get it to work.  As if this wasn't bad enough, the screen turned permanently purple over all of the text as a result I'm sure of the HDMI issue.

I have attempted to change settings to fix this issue, reinstalled the Intel video drivers from Asus' website, and nothing fixed it.  This is not a setting issue but an internal hardware malfunction as you can see in my video.

It wasn't easy to find the source of failure - I guess something in the wiring. The secondary display started to flicker and Console app says: kCGErrorIllegalArgument CGSShapeWindow... After few hours of investigation, tweaking, swapping the secondary monitors and cables I finally swapped the Mini DisplayPort adapter itself for the second one and it worked! I guess it is not so bad considering the cost $4.19 versus Apple's own $99.00 [...] that also FLICKERS! I don't know what to say... I guess buy two or three and see if one of them works.

It is what it is: a low-cost keyboard.  The problem for me, and the reason I'm taking it back, is because the grooves that allow you to find the home row keys are in the wrong place: on the "F" and "H" keys rather than "F" and "J."  On the box they are in the correct place, so I'm assuming this is a mistake.  Still, the lack of quality control is frustrating.

nice looking and bright multi mode! the problem is that the switch was defective upon arrival. various modes of failure, won't turn off, won't turn on, or goes on by itself without pressing the button switch. I loosened the end cap a little and that "fixed" it for a while, but now it's back to the intermittent switch. it's really unusable. obviously from the reviews it's hit or miss if you get one that works.

Item was defective upon receiving. The housing for the arms/spring had to be loosened just a tad to get it to work properly. Of course, me being me, I decided to take it apart completely to see what was wrong with it. That costed me a good 30 minutes of trying to re-position the spring. I bet that would have been funny to watch...

Now that I have "fixed" it, it works just fine.

Bought October 3rd 2016 and Arrived October 11 2016

When it first arrived in the mail,  I opened it up and assembled it right from the get go.  Tested the high beam function, worked fine .  Tested the low beam function, did NOT work at all.  I fiddled the swinging action toggle switch to turn it in the off position and then the low beam MULTIPLE times and it worked "sometimes".  I was a little discouraged that the low beam didn't work ...  So i went to troubleshoot the problem.. I twisted off the lens that held the battery in the body frame,  and I lightly shook the lens cover and I heard something rattle inside.  So I unscrewed the 3 screws that was holding the solid state mother board behind the lens and 4 small pieces of seems to be ceramic pellets fell out.  I really don't know what it was, but that was rattling inside the lens cover.  So i assembled the light back together and i re-tested the low beam and high beam , both functions work perfectly fine now.  I even turned it in low and high beam and shook the light to see if the light would turn off, works perfectly fine.  In conclusion i really don't know what that was, but im sure some of those broken pieces was blocking a connection to the low beam ...  I also don't know if that is an important piece to the equipment...  I have to test it in water now to see if it is water proof.

Pros:  -the light it produces is really really bright
-comes with an adjustable strap that fits ALL wrist sizes
-comes with the batteries already inside the light
-small light so very mobile

Cons: -low beam did not work right out of the box and I don't know if those pieces are important to the equipment

I would reccomend this product to anyone who is looking for a dive light or scuba light etc.  Just be sure to check every little thing this light has to offer and don't hesitate to return the item if you are not satisfied.  These are my opinions to the product.  :)

Speakers are nice and seem to be decent for the asking price.  My issue was that *BOTH* crossovers were screwed up right out of the box.  First I wired my right side speakers, assembled the door & tested.  No tweeter.  So, I disassembled to inspect and test.  Turns out the terminal strip inside the crossover was soldered poorly to it's circuit board and the tweeter would occasionally make noise if you pushed on the terminal just right.  I tore it apart & it looked fine, but after re-heating the connections to the board, the solder further melted in and the connection became stable.

Moving to the left side, I installed the speakers and again assembled the door thinking the first one was a fluke.  To my surprise, none of the speakers in this door worked.  So.....  I disassembled again and found again that the crossover terminals were bad - this time affecting both the tweeter and woofer.  Turns out I heated them up with my iron, let them absorb more solder and low & behold they started working.

Now I'm wondering if after a few door open & closes, temperature swings, etc..  if the little bit of solder I got to run up into the terminal assemblies will again break and I'll be left with having to again disassemble my doors and jack with these things some more to keep them working

Also, my left side doesn't sound as good as the right by a noticeable margin both volume wise and midrange wise.  This could be because of one of three things - significant quality control and manufacturing difference between speakers -or- the crossovers on the left are still not functioning optimally (I have little faith in them at this point) -or- the fact that I only had one XTC foam baffle at the time and installed it in the right side.  I'll be fixing that issue soon and will update my review with the results.  All in all these seem to be decent speakers for the price, but the quality control here is not at all what I'd expect from MB Quart, at any price point.  Have some self respect guys, save the crappy quality control for some off brand speakers next time.

you can make it functional  but spend a little more money and save yourself some disappointment

TL/DR: physically defective, connector pushed right into the casing with the slightest touch!!!! And: kudos for Amazon for a very simple return process (pending confirmation - I *just* submitted the request, but if all goes as stated, yes - thank you for an easy return process).

I'm not one who returns things very often at all. Minor defects don't bother me. I doubt I would've wasted time to complain if this battery had died a year or even 6 months from now, if it had a nick or two, was finicky/tight/loose, smelled funny, etc.... Put in a review, maybe, but not return immediately (well, after creatively swearing at it). No, it takes a serious issue - not a "defective user" or RTFM problem - for me to return anything, let alone spend any time publicly explaining why, and always after a normally-exhaustive process of ensuring I was not simply stupid somehow. It happens. But not this time. It proved defective almost instantly. The battery, that is, not me.

My old laptop is 5+ years old. No real surprise its battery finally bit the dust (if anything, I'm surprised it hadn't happened a long time ago). It's a bit large, an ASUS G53SX "gaming" laptop, that weighs more than a dachshund, and looks like a stealth bomber. As an aside, I didn't buy it so much for gaming as I did to use it as a VM "lab" of sorts, as it's powerful enough to run 5 or 6 virtual machines at the same time with very little resource contention - and I'm a database administrator by profession; it comes in handy to try things out that require a simulation of multiple machines connected to each other. Yeah ok... gaming... is a nice bonus, of course. :) Anyway, the laptop itself still outpaces almost anything on the market now, at least for my primary purposes, so I didn't think for a second about replacing it.. just the battery. I was happy when the new battery arrived.

That lasted less than three minutes.

I popped it into the laptop. I powered it on immediately just to make sure BIOS & Windows would at least acknowledge its presence (knowing full well it needs to fully charge before the battery itself is of any actual use). Nope... "No battery is detected." I pulled it out, figuring maybe it was something, dust or what-not, on the connector.

Nope, nothing "on" it. But the connector looked like it was slightly pushed in. Nah, I'm just imagining that, right? I mean, how often do you actually LOOK at the battery's connector? Maybe it's perfectly normal. "Hey, I'll prove it - lemme just try to nudge it a bit, I'm sure it won't budge even if I lean on it." With the absolute lightest of pressure - as in, a gerbil could've done it - I was able to push it in completely, as if it's not even connected to anything inside the casing.

Now, I know a few things about a few things, and a lemon battery isn't totally unusual. Old/deteriorated cells (maybe it sat on a shelf for a year or four, waiting for someone to buy it), corroded contacts, even a warped plastic casing if it ended up sitting in the wrong place for too long... it happens. If it had been something like this, I'd just ask for a replacement, not a full "no way in [extreme sauna] do I want another one" refund.

But this?????? A physical defect so apparent, never mind inspection of the individual product, there's NO WAY some machine (or person) involved in its assembly wasn't noticeably faulty??? This is not a "stuff happens" incident, it's an incident of complete incompetence by whomever assembled it. In short, my one-star rating for the battery a) would be 0 stars if possible, b) and applied to the manufacturer of this battery as well.

5-stars to Amazon's return process though, I must say.

I bought this because it seemed to have everything I needed for a fair price - it had the power supply, light strip, remote, and IR Wireless receiver for this. Had it all, and out of the box, it seemed to work just fine.

However, after about a week or two, I noticed that my lights started flickering sporadically, and then they would do so more frequently. I would turn it off for an hour or two, and when I would turn it back on, it would work fine again. I also noticed that the power supply that came with it was getting abnormally warm - nearly 130 F. I switched it for another power supply of the same voltage, but lower amperage - it worked indefinitely, but the colors on my remote somehow flipped (Red button turned it blue, Green button turned it red, Blue button turned it green), but all other controls were normal. I switched to the original stock power supply, and the remote behaved normally again, but it ultimately burnt out the power supply. I tried another power supply with a slightly lower amperage, but above the one with the backwards controls, and it worked, but also burnt out eventually.

I then try switching wireless receiver boxes, and keeping the lower amperage power supply (by this point, the original power supply and another one I had tried were both burnt out), and it behaved normally again for the most part - I can leave it on Fade 7 indefinitely, but I cannot leave it on white or the power supply will overheat and the lights will start flickering again.

The sticky stuff it comes with on the back isn't very adhesive, but I found that using that transparent packing tape can hold the weight of this and not be visible.

I am pleased that it finally works, I just wish I didn't have to go through that much trouble.

I got it for $74.99 with a lightning deal. Good price. Got it yesterday. The speaker looks nice, not too heavy for its size.
However, I'm pretty sure I got a defective unit. When I turned it on, the first thing I realized is a annoying background noise (I wasn't pairing it with my device yet). The noise is also there when I played some music It's easily noticeable if I set the volume in my device low. I've asked some others in the Customer Questions & Answers for this device and they said they are not experienced this behavior.
Other comments, it's pretty loud, pretty much comparable for my $20 Logitech 2.1 (not portable) speaker lol, and probably louder than most speakers at the same price range. The bass is there but kind of low.

Item arrived sooner than expected, but the Reader didn't work at all. At first I thought my MicroSD card was the reason (bought it for a Raspberry Pi), but after borrowing a friends reader/writer, it worked just fine in my laptop. After trying their website, and finding out this is supposed to be plug and play (thus they don't offer drivers or anything of the sort in their support website) I realized the reader was simply dead. After I proceeded to return the item, amazon, like always, accepted the return and is processing the refund right now...

So, I'd say don't risk it... But if you feel like you will be lucky enough to get one that works, then for the price it might be just fine... At least we can be glad that Amazon is really good at handling refunds for faulty items.

Purchased one of these drives for my girlfriend's birthday in April.  Tried installing on two different PCs and the eject button didn't work.  Drive was recognized by BIOS and Windows on both systems (XP and 7), but as the tray cannot be ejected it really doesn't work all that well.  Contacted Lite-On support and they blamed Amazon shipping.  Got a replacement from Amazon with the same issue.  I don't believe the packing was insufficient to protect the drive I just believe they have quality control issues.

In Short:
While the cost of this drive is well below the competitors, the effort of going through testing and getting replacements outweighs the cost savings by a considerable margin.

The product works...sort of. I use it to easily switch my mouse/keyboard from my desktop to my laptop without having to reach behind my desktop to unplug the keyboad while keeping wires out of the way.

When both PC and laptop are on and connected, the switch works great. I can switch from one PC to the other in about 1 second.

However, there are a few issues, with one being pretty major: this device caused my desktop PC to exhibit strange "sleep" behavior and could have caused loss of unsaved data if I wasn't careful. When this device is plugged into my desktop, it doesn't go into suspended power mode, and for whatever reason, my PC shuts down 1-2 hours after going to sleep. Unless I were to shut my PC down instead of using sleep, this product is now unusable, as I was unable to find a workaround.

A note about quality: I opened this thing up after I gave up on it, and it is a tiny PCB with maybe 8 solder connections. My point is, this is a very cheaply made product that could have been made more reliable by making better/more reliable circuitry.
