Mini 2-LED White+UV Flashlight Keychains (5-Pack)

Pros: Four of the units worked flawlessly, the last, not so much. More on that in cons. However, for the price, I was still pleasantly surprised. The single LED at each end is fairly bright, and would make a good keychain or purse light. As advertised, one end is a white light, the other is UV light.

Cons: The body of the unit is plastic, very light weight. Trying to disassemble the light for repairs is not all that easy, but it can be done. The mechanism is simple, though probably would cost more to buy batteries than to just get another order in. (each end of the flashlight is power by three separate batteries - for a total of 6 in each unit)
The switches protrude quite a ways, and are weak. Don't expect these to last too long, but, they should provide service-life that will make it worth the tiny price.

Other: Cheap price, cheap product, priceless fun. A good deal as long as you know what you're getting into!

Pros: It's very cheap and comes with batteries so its ready for use from the very beginning.
The two features (standard light and UV light) make it a little more useful compared to other light keychains. The presence of two different buttons make it really easy to use.
While it lacks on some points, it's somewhat good from the electro-mechanic point of view.

Cons: This item is not cheap only on price but also on materials. The case feels fragile at touch and probably will prove fragile also on use. I don't recommend use it as a keychain since a keychain is often subject to high stress levels.
The two buttons are of cheap construction as well and is quite easy to strip them off (by accident, for example).
Taking a look inside extracting the two leds, you'll realize soon that inserting them back into the case is quite a difficult task so changing the batteries can become quite challenging.

Other: Cheap materials and cheap price. I don't recommend to use this item as a keychain. Still, it can be of some use and has no lack from the electro-mechanic point of view.

Pros: Well its got a white led and a UV led, they are both pretty bright, and it has a keyring

Cons: I had one of these in my pocket for a few hours on my keychain, two things happened... 1) The keychain broke off, the big ring part broke off the chain, i didn't take a good look at it but it looks like i can just put it back on and maybe bend it to hold it. 2) the black buttons, are nothing but a stick with a part that sticks out all around, and came out in my pocket... its easy to put back in but it'd probably fall out again

Other: Its an okay deal, if you keep your keys on the side of your pants (with one of those buckle things (see sku.33427)) or you are giving them to kids or something, otherwise i'd go with something else

Pros: The items come perfectly packaged in one blister per unit.
Light is good, and batteries are included so you can start using it right away. The rubber buttons are comfortable and easy to use, even for young children.
They are very lightweight.

Cons: Build quality is poor.
You can find some edges from the manufacturing process, and adjustments among the different parts are lousy.
Besides, the rubber buttons tend to get stuck inside or come off easily. Putting them back into place is sometimes easy and some other quite tricky.
If you have to open the item to replace the batteries or put back inplace the buttons, you will see that the closing thread is quite poorly made, so do not expect to be able to open and close it many times unless you are always very careful.

Other: A small improvement in build quality could lead to a very desirable product. Also a design improvement to make it safer for kids would be nice.
