Question: What type of batteries does this product need?
Document: The lights are very bright when you first instal the batteries, but it doesn't take long for the batteries to burn out. The Velcro didn't hold well on the underside of my cabinets. Screws came with them as an alternative to the Velcro, but it wasn't worth going to that effort when I wasn't happy with the product. I can't honestly recommend this product.
These lights make a special addition to dark areas - just peel and stick (but need batteries).
Don't know yet how much they eat up batteries...I've only been using them for a little while...but I turn it off when I don't need it and only turn it on when the phone rings or I need to dial out. The price is right, though... But if you really need some light, look elsewhere.
We bought these lights to help out at night when we go into a bathroom or hall and just need a little light to see our way around. Once you attach the light a simple twist to the left will separate the back plate from the rest of the housing to access the batteries (or for us mobility). What made these little items indispensable was how they helped out during a crisis.
I combined these Click n' Stick lights with other emergency power lights that plug into receptacles around the house (bedroom, bathroom, kitchen, dining room, den and living room) and automatically come on when the power goes off.You just have to make sure that you keep good batteries in them. Check the batteries once a month.Of course, anyone who is well prepared will need flashlights, too. I recommend the ones with multiple LED bulbs.
I've used similar looking LED stick on lights before, but these are much brighter and whiter. Very good product at a very reasonable price.
I purchased a similar product at my local hardware store. They were awful, and I returned them. Then I ordered these and was very pleasantly surprised. These are easy to use, don't fall apart, and they stay where you stick 'em. The quality is very good.
This product was a big disappointment. It was purchased to light up a small section of my kitchen counter where I like to do my reading. There is practically no light coming from it. I can't use it and it will be placed with the many other useless products I have purchased on the internet.
I was very skeptical about purchasing these lights since they were an "As Seen On TV" product. I needed inexpensive battery operated lights for paper lanterns for my wedding and these are beyond perfect. They are BRIGHT and stay bright! I tested one out for 24 hours and it stayed bright.
Not what I expected;  however, 'As Seen on TV Guys' (that I purchased from) have great customer sevice & communication (not to mention less expensive than if you bought from infomercial! )...Would'nt recommend this product for my purposes, but highly recommend this Company for their great customer service!Will definatly buy from them again!
