Great while it lasts, then works again...

The shower head replaced and older shower head, easily attached to the old hose, and fit nicely into the bracket.  The pressure is quite good and the turbine did not make much noise to generate power to power the LEDs.  The LEDs are bright and entertaining as described by others.

However, after two weeks of approximately daily use the turbine started to buzz and the lights no longer work.  The water temperature is reasonable (set to a maximum of 115F)  and the county water quality is not particularly hard or turbid, so the cause is unlikely to be overly harsh conditions. The design is fused plastic, so it looks to be unserviceable.  The only diagnostics I have is that there is a momentary flicker of light as the air is pushed through the head, but once the water starts the lights stay off.  Probably the electrical connections are intact but the turbine cracked or became unseated due to poor quality control or a defective design.

Update:  Vendor has offered to refund or replace.  I am giving them a second try and will update review upon testing of the replacement.

The replacement arrived and seems stable.  I recommend the product based on prompt vendor response to an issue and the joy it gives my child.

I have now gone through two of these. When they work, they are fantastic. Unfortunately the electronics in both of mine have died after a few months. The first time I thought it was just a fluke, but my second tuner is now continuously flashing random screen segments whenever I turn it on. I tried replacing the battery but that didn't help. I'm going to give the Snark tuner a try. Maybe I will have better luck with that.

They're great when they work, but mine stopped working after about 8 months.

Great for the first year or so, then it constantly won't turn on/resets/dies. Wish it lasted a bit longer prior to having to throw it in a landfill!

I purchased the FOB in July 2014 and it worked great, if I was next to the car, until a month ago.  It stopped working so I took the back off and put it back on, and it worked great again.  Two weeks ago, it stopped working again.  I even replaced the battery this time, but it still won't work; and because I have to use the key to unlock my door, I have set off my car alarm a couple of times by taking too long to get in. I will be buying another one, but I give this 2 stars because it did what it was intended to do, although it could have lasted a little longer.

The unit worked pretty well for a year, then just stopped working

I've had this product for ~16 months and have found it to be ideal.  It is compact, bluetooth worked flawlessly, connected to my iPhone without fuss, was able to transfer to another car without problem.  Then, just last weekend, the bluetooth stopped working.  I hadn't done anything with the device; it just ceased to function.  I unplugged it and reseated the device.  No go.  It still charges the phone, it still glows blue, but I cannot see it with any of my devices.  It is as if the device doesn't exist, so I am assuming the bluetooth is no longer functioning.

I contacted the vendor (New Potato) and they told me "Unplugging and plugging it back in is the only way to reset TuneLink.  It sounds, though, like Bluetooth has stopped functioning.  Unfortunately, your TuneLink is beyond our warranty period.  However, we can offer you an out of warranty replacement that comes with a new 90 day warranty.  The price is $49.00 plus $7.99 s/h."

OK, while I appreciate the opportunity to purchase a refurbished unit for less money (but with only a 90 day warranty?), I am unhappy with the fact that a product that has almost zero "wear and tear" on it suddenly stops functioning within a couple months of an arguably short warranty period expiring.

I love the product, but poor longevity and warranty.

OK, call me stupid, but I bit and bought a second one of these things figuring I had a bugged device and maybe a new one would work.  I've owned two of these things now (I should have learned after the first one) and they both failed.  The first one failed after ~16 months, and it failed outright.  The second didn't completely fail, but it works inconsistently, and it did it after only a couple of months.  I have found the device drops the bluetooth and/or won't connect to my iPhone4S.  I've also tried other iOS devices and it won't work.  I've tried other cars and it won't work.  It must be the device.  I will NOT be buying a third device, which is a shame as when it works it works GREAT, even with my in-car bluetooth handsfree connection.  I love this device when it works.  Very, very sad.

Bottom Line: Junk - Reduced to one star.  Don't buy

Like a lot of reviewers described--this is convenient, easy to set up, and works well as a second monitor or to project your screen onto a larger screen...however, how many reviewers are reviewing this only after the first several months? Mine worked well for about only a year before the USB port was no longer was registering.

In the last few months, I had to shift the monitor around or tape the usb cable onto the port to use the ir...this lasted for a few weeks before it no longer worked at all. I was careful with the item, but I had to unplug and replug the cable a lot since I traveled for work--just from unplugging/replugging the product seemed to break too easily. I use many, many other electronics with the same USB/micro-usb or similar port and they all lasted much longer.

Honestly I liked the product, but it did not last long enough for the value.

When it works, it's great. But given that actually using it for any extended period causes it to disconnect, I'd say it's pretty useless.

Worked great while it lasted, but several months after purchase, stopped working altogether.

Worked Very Well for a Time, failure rate seems a little high to me.

Great (small, functional), until it stops working..
I bought two (in a year period) then switched to a different watch.

Great Product, Works Great, Lasted about two years

This SD card reader works great when it works. But after a year, it failed to be recognized in Windows and no drive letter was created. Moving to other USB ports didn't help. I contacted Anker and was offered a replacement under warranty. That worked fine for another year, then failed to be recognized again. I noticed that it still works if I connect it to a usb 2.0 port, but who wants that kind of speed nowadays. I think there is a reliability issue. For the low price of $8.99 when i bought it, I guess it served its purpose and I can write it off as a loss. But I would look elsewhere for something more reliable and less prone to breakage.

Update on the "unable to be recognized by Windows" issue: I downloaded and re-install the " Intel USB 3.0 eXtensible Host Controller Driver" from Intel and it works again. However, I keep having to do this every few weeks. Could be something not right on my system. But if others experience the same drive not recognized issue, try re-installing the Intel driver.

Hint: If I can give one advice on keeping this device working longer, I would suggest don't hot plug the device at all. Hot plugging is disconnecting and connecting a device while the computer is on. Both of my devices died after I started moving the reader from computer to computer and various ports on the same computer. So if you have to reconfigure, shut down the computer first. You shouldn't have to shut down normally, but this device seems prone to hot plugging failure.

I've used this Mountek CD slot mount almost every day for six months on a 180-mile round trip commute. For five and a half months, it worked great, holding my phone (first a Nexus 5, then a Nexus 6p) very securely. However, in the last few weeks, one of the internal gears has stripped itself, and now the two adjustable "wings" that clamp the phone don't hold properly; they pop outward far too easily, so even hitting a small bump in the road will send my phone flying.

I took the entire thing apart, and was able to temporarily fix it, but the plastic gears have worn down too much and it failed again within two days.

The part of the mount that secures the mount to the CD player slot works great, and seems unlikely to mechanically fail. Too bad the part that grips the phone didn't last.

Wonderful when it works,  frustrating when it doesn't
This mouse looks nice, feels comfortable, tracks well, and turns off when you fold it to a compact form.
After 2 years, it started to flake out, and lose connection to the laptop a few feet away, it comes and goes, regardless of distance, batteries, power cycles, USB plug....  It was nice while it lasted.  I plan to buy another, and hope I have better luck.  (I've owned over 20 mice for my various computers, and this is the first one I ever had die on me)
