Could Last a Lifetime
I purchased a Sylvania Silver on June 7, 2006 (over two years ago at the time of this review) and it's still going strong on the same set of batteries! My wife and I decided to place the unit above our shower stall due to the minimal light available in the area. Although we hardly use it daily, it gets reasonable use and possibly abuse due to the fact that it probably wasn't designed for such an area. Remarkably, the unit has yet to require a change of batteries and the adhesive is still holding strong. Three LEDs are hardly enough to light-up a room, but adequate enough for our shower stall plus the added advantage of it not being able to electrocute us. I can see how the batteries might be difficult to replace but, seeing how little you may need to change them, I consider it a minor design flaw. I highly recommend this product.

It doesn't stick well
I tried to use it on my car trunk but it doesn't stick well, especially in warm temperature. Another not so useful junk in my garage.

Great accent lighting
In case you're wondering whether or not this is for you, this should help. These are great for ACCENT LIGHTING, not bright work lights. They contain daylight LED "bulbs," so they're bluish in color, not a warm yellowish light. I happen to have blue tile countertops in my kitchen, so I bought them to accent some of the wall decorations on one side of the kitchen. For that use they're perfect. As worklights they're simply not bright enough. Also, their adhesive sticky side needs a good firm push onto the surface to which you'll stick them, otherwise they WILL fall. One annoying thing that kept me from giving it 5 stars is the fact that you have to unstick them to replace the batteries. If you're considering accent lights without the mess of wires, then these are for you. I happen to love them, my wife not so much. Maybe Sylvania will consider making them in white.

Sylvania Dot-it Self Adhesive Bright White LED
Was expecting a lot more from these. The purpose of my purchase was to add additional light to a bi-fold door closet. Found I needed at least 6 of them in a 23" w 7'3" h section of the closet to provide minimal light at best.

Bright idea, not bright light
Perfect idea and have so many places to use it, but the light is just not bright enough. More of an accent light if anything.
