3-in-1 Red Laser + White Light + UV Light LED Flashlight Keychain (3*LR44)

Pros: Ever tried to check your yellow print from your inkjet printer? Than you really need this! When you shine with the blue led on the yellow print it will come out as if you printed black!

Cons: The build quality is not so great. I've used the hook to clip it to by belt but that also is the cap for the batteries and comes of real easy. I would suggest to glue it to the body and just order a new one when the batteries go dead. Also the switches are very light to press so you could turn it on by mistake.

Other: If you need to work on inkjet printer regularly you really need this to have a good judgment on the yellow print. for that price it's great!

Pros: *Cheap, very cheap
*Very useful with keys, asy attaching/disattaching rings with keys
*LED, laser and UV in one, makes some fun to use it when you have nothing to do with yourself :P

Cons: *Very poor quality - the battery cap kept falling out of the rest, causing batteries to get lost
*The LED/UV button could be somehow hidden, in a pocket it keeps to turn on causing batteries to run out

Other: For this price it is worth buying, even if it has such poor quality.

Pros: Three lights are included in one handy little flashlight. The laser light is bright and the button is easy to push. The LED and UV lights are on the other button, and the unit comes with a little removable protector thing that keeps you from accidentally turning on the light and running down the batteries.

Cons: I haven't really experienced a con yet. The other review says that the battery cover comes off easily, but mine is nice and tight for now. The caribiner is not the greatest build and doesn't spring right back to the closed position properly (it's a little crooked and you have to push it to the side to get it to close).

Other: Cheap. Useful. Works great. What more could you ask for? If you need a little flashlight, this one would make a good choice.

Pros: It's a really useful laser.
Works.
Comes with a cool blue key chain.
The build quality is good.
3 working modes: red laser, uv light and white light.
It's cheap.
Batteries included.
You can use the laser and the white or uv lights at the same time.

Cons: At first the white and UV light weren't working. I fixed it by replacing one of the batteries.

Other: As stated by the manufacturer, the laser characteristics are:
Max output < 5mW
Wavelength: 650nm +- 10
Class: 111A

Pros: - 3 modes - extremely small and lightweight - comes with a simple snap hook to attach it to keyrings, belt loop, backpack, etc.

Cons: - cheap plastic enclosure - flimsy buttons - not very strong light (but that's due to the batteries) - the focusing of the laserpointer isn't too well

Other: If you are looking for a small and cheap UV light and laserpointer, this is your way to go. Not recommended for professional use though.

Pros: Great price; Well build; Laser works great. My pets loved it. It is very funny to play whit the cats; Battery is lasts for more then one month; The keychain clip is a bonus; It does not heat when used for long periods, and the red dot do not get weak.

Cons: LED Flashlight is not so strong (One LED only, powered for LR44 batteries. Can't be strong);

Other: If you want to play with your pets, this is a great toy. They love to follow the red dot in the floor or in the wall =)

Pros: -3 functions attached to a portable keychain -Very useful and portable -Cheap -Good looking -Batteries included -The clip is good for attaching it to the keys or to a bag -One button for laser and another for LED/UV

Cons: -The build quality in general isn't that good, but I can't complain for this price -Clip is made of plastic and looks fragile

Other: I'm satisfied with the product. I like the color and the fact it's 3-in-1. The only things that worry me is about the build quality, but for this price I can buy another anytime!
