If you are lucky you will get 2 uses out of the item.  HORRIBLE would never purchase again and do not recommend.  I guess I should have expected it by the cost.

Out of the 10 I got 5 didn't work. Extremely disappointed. I don't have money to waste and unfortunately this isn't the first time I've gotten bad ones. I guess time I order different ones.

These came in a pack of 2 and one didn't work.

Only 5 of the 6 shipped worked, the one that does not work has all of the insides rattling around and the others that work dont. What do I need to do to get another one?

I didn't give the full 5 stars due to some of these were received defected. Some of them perfectly and others work to a degree. The ones in question work like they are about to go out, they flicker like a strobe light. I contacted the Seller, SHINE BRIGHT and their response was, " Hi, Sorry this order was fulfilled by amazon. Please contact them for this matter. Thanks and have a great day." So they have washed their hands of the situation and wish to have nothing more to do with it. Buy at your own risk.

Half of them didn't work. I had already installed the others. Therefore, I didn't want to go through the hassle of uninstalling them to return all of them.

Loved them.  I bought 4 10 packs and of the 40 devices there was one that didn't work... not bad for the price!

This one works tooooo.  Oh my 2 out of  four.  What are you going to do about the other two items that don't work??????

I thought it was a good value but half of them don't work. Too much of a hassle to return.

We have only used 5 of the 10 bulbs ordered but out of the 5, one did not work.

2 out of 6 don't work. Would return but already gifted 2. I hope those work but have no confidence

I order five of these and finally got them up....months after purchasing them.  They are NOT easy to work with....After hours of work, I discovered that only TWO of the five ordered (and they are not cheap)...but only two worked.  The other 3 just did not turn on....ever.  Seems it is a 'difficult' item to return.  I AM NOT HAPPY.

Happy with number one so I didn't hesitate to order two (2) more at one time.  The second two do not work one iota.  (One for us, the second a gift).  I hate using my time to return anything especially when it is such a simplistic product that should work.  I think they should be tested before being packaged.  Sadly I will order two more and it will be a crap shoot, wish me luck!?

I purchased a set of them. One of them does not work. The one that does work is very bright and very responsive to movement. I just wish I would hsve received two working ones!

Some worked some didn't. The ones that work look great! Would give 5 stars if the company wasn't so hard to get ahold of to try and get the ones that don't work replaced. Only been a day I'll update on whether others are working or not in a month or 2.

Update: changing to 5 stars. The bulbs still work and the company contacted me regarding the bulbs that didn't work. Also someone broke into my truck and they still replaced the bulbs even tho I could not send the broken bulbs back!

3 out of the 6 worked, one I was able to pull apart enough to untwist the ribbon.  Had the same thing happen to a bic brand I got at the local drugstore.  I will try a different brand next time.

Some work right out of the box button click or not. Some take several days of bright light to function as instructed. They seem to have individual personalities. Moved some around and will check tonight
