Bests & Worsts Reviews from Amazon

I won't go into great detail about the product because others have alrady done so, I just wanted to speak to the negative comments. 1) Not designed for the Kindle/doesn't work without obstructing the buttons or the reading page. I'm not certain what these folks are even talking about, frankly. Perhaps you have a different version of the Kindle than I do; I have the 2nd generation white one. If you clip the Mighty Bright to the top of the Kindle with the battery pack at the back (the little padded end of the clip toward the front) it stays on just fine, it doesn't cover any buttons or the reading page. I have since purchased a Kindle cover and I now clip the light to that, so no issue at all. 2) There is a reflection on the screen. If you have it clipped on the top of the Kindle, simply raise the arm a little higher and position the light itself perpendicular to the Kindle (so it is shining down like a street lamp) not twisted down where the light is pointing directly toward the page. This gives plenty of light to read by, and no glare. 3) You can't travel with this light because the button is so sensitive that it turns on and drains your batteries. I have traveled with this light quite a bit and it only turned on by itself once, when I had it crammed at the bottom of a large, soft sided carry on bag. There are several simple solutions to this. Don't pack it an overstuffed bag,don't put it near the bottom of a bag, or...simplest of all....take the batteries out when you pack it. I don't see how that is such a great inconvenience! If you have it packed that deeply/tightly in a bag/suitcase/backpack you are obviously not using it en route, and putting the batteries back in when you unpack shouldn't be that big an issue, and if you are using it in route, put it near the top where you can reach it easily and nothing is likely to accidently turn it on. My wife carries both this and her Kindle in her purse regularly and never has a problem. The light is lightweight, bright, easy on the eyes, cool to the touch and takes standard batteries. As far as battery life goes, that depends on how long yout run the light, whether or not you use both l.e.d.s and how good the battery quality is you buy. I have had mine for 8 months and I will be changing the battery for the 2nd time, soon. Not bad for using it nearly every night. I'm thinking of switching to rechargeable batteries, though as we use so manyof them in our house.
