I was thrilled to receive the Kindle this Christmas, and 3 weeks later, the MightyBrite XtraFlex2 Clip On Light to go with it for my birthday. I took it out of the package, put in the required 3 AAA batteries, and was extremely pleased with how much light this little thing put out. I am in a lot of situations where I am in low-lighted areas and try to spend that time reading on my Kindle. This thing was going to help a ton in those situations!
I used it one evening for about 2 hours, turned it off, put it on my nightstand and went to sleep. I went to use it again the next day, only to find that for whatever reason, it no longer works!!?? WTF?! I turned it off, so the batteries are just fine (and yeah, I double checked just in case). Didn't overly flex the neck of the thing. It just doesn't work.
Wait, scratch that, it will randomly come on for no reason at all if I have pushed the button to turn it on, but I have no way of telling if I've done that or not as it doesn't come on right away, it just turns on whenever it feels like it I guess. And only 1 of the 2 lights work.
So take that for what you will. I guess the majority of people have good luck with it and maybe I got a defective unit, but 2 hours out of the box worth of usage before it dropped dead on me just wasn't worth my time or money. Sending it back, will look for something else.
