first one I bought stopped working altogether after less than an hour. Bought a second one....see how it performs. Maybe I received a lemon first time.

Second one stopped working after only about 1 hour of use. I would not buy this light again for a fraction of the selling price....garbage. Don't be sucked in by the inexpensive cost. Its not worth the price if it doesn't work.

update: got the second light and all seemed good. I haven't even used this enough to drain a set of batteries. I go to use it today and it comes on only to go out after 10 seconds. Hit the on button again and only lights for ten seconds. Change batteries and the same thing. Naturally I cannot return it now being past the 30 day policy. What a waste of money.....Amazon needs to only allow quality items not all this junk that is being made in inferior factories. Don't get lured into the low cost purchase price as I was. Quality products come with more than 30 day return policies.

My first device was defective and stopped working after less then a handful of uses. I'm not sure about the functionality of this device, I question if it works properly. I contacted customer service through Cappec and they sent me another device, though I would have really preferred a refund.

Second one!!!! First one simply DID NOT WORK!!! So, I returned for a new one. I tried to do a first charge and the charging port broke and fell inside the transmitter. I'm returning this again and won't be getting another.

this is the second one I've purchased.  The first one just stopped working after 2 months.  I didn't keep the packaging and recite for the first, but I have for this one.

Got a replacement sent to me after this first one stopped working after only 2 uses. I received the replacement very quickly, hopefully this new one will last much longer. I understand that there are faulty units out of every batch, pretty sure it was just a bad connection with the switch.

Bought two of these and one completely stopped working after three weeks. Other than the 50% failure ratio it works as advertised

Bought two of these less than four months ago. One already stopped working. Double checked it in different outlets and with different usb plugs, but it just stopped working for no reason...UPDATE- I noticed there is an 18th month warranty, so I called their customer service and a person answered!! I was expecting a phone tree and a long wait. I just gave the rep my order # and she said they were going to mail a replacement out. The whole thing only took a couple of minutes! I'm impressed so far and hopefully the replacement will work better.

It worked well for a little. But when it stopped working they immediately sent me two brand new ones without me even asking!

I purchased this before and it works great! I purchased a second one and it has stopped working after only a little over a month!  Not sure why but the spinning mechanism in the middle stopped operating properly.
