I got the Clip on LED light for my Kindle in March of 2011. Its been four months since then but I must've used the light less than 10 times.
It seemed good at first, but later (maybe after 5 uses) the bendy neck became loose and wouldnt stay in one place.
Yesterday, I tried using the light again, only to find that its stopped working and the batteries were overheating. I tried replacing the battery with new ones, but they wouldnt work either.
I would not recommend this to anyone. Dont get carried away by the price (its increased by £2 since I purchased it) instead go for something that is of a better quality.
Unfortunately Amazon doesnt have a negative rating and I am stuck with giving 1 out of 5 stars. If I had it my way, I'd give it -1 instead!
