NanoLite: The World's Smallest Key Light (Single Pack)

Perfect solution for a dark entryway. Easy to attach to key and easy to use. Note: be sure to clean key surface with solvent to remove any oils before adhering the device. Also, put the button on the thumb side of the key (are you right handed or left handed?)

I'm editing this review to add that the light does work well, it lights up the whole lock area. But on the second day the black cover fell off leaving the battery and little wire exposed. Wasn't in my purse or pocket, so had to tape a button over the battery to use it until I find something else, (see photo). Didn't lose much since it was only a few dollars, but it was still money thrown away.

The red light is bright but I wish it was a white light. After the third day on my keys the case that covers the battery fell off. The cover is just held on by double stick tape which sticks to the key too.

The light is small enough to fit onto my key ( I have a key with a large "head") without being too much of an hindrance when I use the key. The light is bright and so far (I have had the light for 6 weeks) it is holding onto the key very well.

excellent little gadget... works as described and stays on nicely. doesn't get in the way when i use the key

very useful to have around on a dark night. The adhesive is like Gorilla Glue tough and the product has yet to even given the illusion of being loosened from the key despite having the keys tossed about on to my desk, in pockets, etc. It is SO much nicer than having one of those annoying little keychain lights that you really can't use without dislocating fingers to use it and the key simultaneously. This light is so easy - just a small bit of extra pressure on the key you are already holding, and instantly you are given a very nice amount of red (easy on the eyes) light to see the lock.

I was super excited to order this and received it quickly, but within two days of having this attached to my key on my key chain, it broke into pieces and the battery and the little light bulb fell out. I don't think I"m any rougher on my keys than the average person, but I expected this to hold up a lot longer. At leat it was only a few bucks.

Fell off after about a month on my key ring. I liked it while it lasted though, hopefully others have better luck!
