Using this rather than returning it. UPDATE- DEFECTIVE, read comment

Why?
1. Dishonesty - it is only "quiet" if you leave the very thick, hard-to-see-through waterproof(!!!!??!!!) rubber cover over the KEYS!
2. 1 battery in mouse, 1 in keyboard. This equals more frequent replacing than the keyboard/mouse I replaced which had 2 batts in each.
...otherwise it works as expected, but I could've spent $10 less (and did) for another brand I am MORE happy with. Using this rather than returning it.
  UPDATE- Right mouse button only works if pressed repeatedly. changed battery (3 days) no good.

Upon receiving the iwerkz  Keyboard I charged it from my PC USB port.  After 2-3 hrs. charging, I noticed an electrical smell coming from it.  I immediately unplugged it and left it alone for a couple of hours.  I then tried turning it on and the status light came on but would not go off.  The instructions said the light should go off in 4 seconds and then it would be ready to pair.  I tried pairing anyway but no go.  I then hooked the charging cable back up, turned it on and the status light came back on and went out after 4 seconds.  I was able to pair it with my Xoom and Asus MeMo pad Me173x and it worked great.  After it was off for several hours I tried it again and it would not come on.  I again tried the charging cable trick again and it started working as per instructions. For a few days I could get it working by the above method but the status light would start flashing and it would not stop.  According to the instructions this indicates it is trying to pair.  I ended up returning the keyboard for a refund.  I rated it 2 stars because this is a great little keyboard, when is was working, and I suspect I just received a defective device.  Amazon has a great return policy.

UPDATE:  I purchased another iWerkz keyboard and it paired, as per instructions, with both of my tablets.  I use it primarily with my MeMo Tab.  I charged it with a wall charger that came with my LG Bluetooth headphones that I bought for my PC.  So far it is working perfectly.

I love this but I cannot use it.  I am hoping it is just a defective one as it fits good on the button/knob side but looks crooked and does not seat properly on the left side which creates a weird look and a gap on the left side of it. I have taken it back out and reinstalled several times.  I was able to get it square once, but within 30 seconds it was, again, not seated correctly.  I started the return process.. I am reluctant to try again.

Update: The seller contacted me about the faulty item and shipped a new one to me for free right away. I'll update the review once I receive!

------

I use this at work and after three days, the blue indicator light is not illuminating and it will not charge.

The power button wasn't seated properly on the device so it can't be powered on. This was a Christmas gift and is unusable, so now we are out a gift and the money spent.  Amazon stated that this item isn't eligible for return..  I suggest that if they're not going to allow returns on battery items that they check to make sure that it is working properly before it is sent out to the buyer.
However, I called Amazon and explained  the situation and they are sending a replacement free of charge and no shipping cost. They said I could do whatever I wanted with the defective one. I wasn't  expecting that and was very pleased with the outcome.

I bought this on May 20.  It worked great.  I used it about 8 or 9 times.  Just tried to use it again and it is not working.  Not happy.  Past the return date now.  My computer does not recognize it anymore, and it just shuts off automatically.

There was a rattling sound inside of the machine and I should have returned it immediately but it worked, so I didn't.

Update--upon seeing this review, the company contacted me and informed me that my purchase is still covered by their return policy, and they have automatically sent me out a new one.  For such good customer service I have upgraded my rating to 3 stars.  I will change it again when I see whether or not this one lasts.

Update:  I am now giving them 5 stars---they saw my review, and took care of me.  That's awesome.  The new machine works perfectly

Like the title says, there is a defective connection in this toy that often shows up.  I would have slap it with my hands until it would turn on.  Then it would work for a while.  Unless you like returning goods through the post, its probably not worth the trouble.  On the other hand, it would have otherwise been perfect for us.  So if you take the risk and you get lucky, it could be a good deal.  maybe.

Didn't work properly, I had to return and order another one.

I initially posted a review that was not in favor of this. While the item arrived broken, the seller did refund my money

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.

Screen has a deep gauge in the upper right corner. Returned immediately. Disappointed.

This is an update to my original review. Seller has good communication. I returned for a refund. Seller offered replacement but I was under a time crunch and opted for a different product. This product is likely better a bit better quality than the alternate product I've settled on. However, I think the alternate suits my lower tech travel preferences-e.g. I don't need remotes or gaming accessories. Apart from the gauged screen, the display was pretty good.

**Update**
I'm bumping up my 3 star review strictly for the customer service. 2 days after writing my review, I was pleasantly surprised to have a replacement bladder delivered.

I have not had the opportunity to use it yet, but already the button seems more stable. I will provide an update after a few uses.

*****
First use: took probably 10 tries to properly seal the twist cap. I finally had to press it down hard top and bottom before twisting. Otherwise no other issues and I loved this bladder.

Second use: only took 2 tries to lock in the cap and held it upside down to ensure no leaks. I stick the bladder into my camelback pack (fits perfectly and hooks in place). Toss my pack on the bed to put my shoes on. Pick up the pack and my bed is soaking wet! I pulled out the pack and the hose is partially separated. I figured it must not have snapped in like I had thought. Snap it back in, hear the click, and off I go!

I arrive to the trail and my bag is still wet, I think it just hasn't dried yet. So I start my hike. Halfway up the hill my bottom is suddenly very cold. Strange I think, but maybe my clothes are absorbing the water from the pack. I go to drink,  there is zero water coming out of the hose and it feels like pressure building.

I remove my pack to investigate and realize my pack and bottom are SOAKING wet. The quick release button has partially released the hose again. I snap it in place for the 3rd time with a little click confirming it's connected and can finally draw from what water is left in the bladder. Without proper water, I cut my hike short head back looking like I've now peed my pants.

I get home and investigate, barely touching the release button and the hose pops right off. I turned it upside down to make sure it wouldn't leak if the hose were to separate and no issues...

My problem seems to be that the button is only partially releasing the hose while putting the bladder into the bag. I feel this is a design flaw and the release should be a pull vs. button to ensure its not an accidental release.

Before today I really liked this bladder and had a second one in my shopping cart ready to purchase for my other bag, however, I will try this one more hike and if I have the same issue, it's off to a different brand.

This is the second time I've purchased this unit and the second time it's arrived to me defective. Hooked it up, confirmed correct AC input with meter, zero output, with no green LED. The most baffling part is that the first time I ordered the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/BMOUO-12V-30A-DC-Universal-Regulated-Switching-Power-Supply-360W-for-CCTV-Radio-Computer-Project-LED-Strip-Lights/dp/B01EWG6YT8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">BMOUO 12V 30A DC Universal Regulated Switching Power Supply 360W for CCTV, Radio, Computer Project , LED Strip Lights</a>, which is apparently a different seller, but it arrived with the EXACT same defect. See pictures. The enclosure is dented on the same spot. As far as I can tell there is zero difference between the two also.

Unfortunately, this is the only type of unit that I know of that will work with my Anet A8 3D printer. I tested the new one right away so I'll be getting a refund and a 3RD replacement, not happy about it but I don't seem to have any options. The first unit I had to wait to test and my return window closed, money down the drain.

My hunch is that the units sold by EPBOWPT and MENZO are also exactly the same, and the different reviews are just luck of the draw. Leaving this review on the BMOUO unit as well.

If you need buy this, good luck and test as soon as it arrives.

Mine seems to have been defective and I did not want to bother shipping it back and paying for the shipping. I hate giving bad reviews but...

The left mouse button seems very difficult to work with.  When I press it down it does not seem to be connecting correctly.  I end up having to press it down multiple times before it makes appropriate contact to work.

I want to return this item for a refund please.

===========================================

Edit:
First, I want to thank you for the return labels and authorization provided. Secondly, I was astonished to see I only had until the end of this week for the item to reach the return address. The label clearly indicated that: "All the items must be returned by February 3, 2013"

Since the return paperwork indicated that I only had until February 3rd for the item to be received at the return address I am concerned because that date is a Sunday and there are no postage deliveries made on Sundays.

I am a little concerned. Please advise if there can be an extension to ensure the item actually reaches the recipient on time.??

Additional information:  Please be aware the shipper of this product did not include a shipping/packing slip.  When I opened the box upon receipt, I noticed that the package had already been opened once and re-taped closed.  Apparently due to being shipped from overseas, I have to assume someone in customs may have opened it, so I have no idea if a packing slip was originally in the box at all.  When I got the package, there was no packing slip included.

I didn't see an option to contact the seller. I would like to exchange it for a good one since the one I received is defective. Would prefer an exchange rather than a refund.

Old Review 1 star (updated bellow)

I was in love with this, but just 2 days after regular use and it stop working.

I purchased it based on the great reviews, and I have to admit that this is the first time that something like this happens to me with a product purchased through amazon.

In the attached image you can see the device connected to the energy with no signs of life.

Update:

I got a full replacement from Alisten, and as of now it's working as expected, the Sales Manager was very attentive with the issue.
