Pros: These lights are incredible! These flashlights are fairly small but they produce more light than most keychain lights. Compared to my Streamlight Nano, I'm guessing these keychain lights are about 15-20 lumens. The price is also great. For 10, the price works out to be about 45 cents per light which is a fantastic deal. I gave two of these lights to my brother and he immediately bought some more for himself. Size-wise, these lights are fairly small and lightweight. They're about the size of a real Photon light and can easily be attached to your keys, backpack, neck lanyard, etc.

Cons: Nothing. These lights are excellent! (However, it would be nice if the flashlights have a strobe function but I'm just being picky.)

Other Thoughts: Lights are shipped OEM in a bubble envelope. Some of the screws may be loose so when you receive them, tighten the screws with a micro screwdriver. The white version releases a bit more light than the black version. Of the 10 lights I received, only 1 had a sensitive LED but this was easily corrected by opening the light and readjusting the contacts.

Bottomline: These lights are a MUST HAVE. Don't be fooled by the low price, they are the BEST keychain lights DX has to offer. Buy 10, 20, or even 30! Keep them all or give some to your family and friends. You never know when you may need a flashlight so hang some on your keychain, backpack, jacket zipper, etc.

Pros: Great little torch light which lights up very brightly just as everyone said. Quite surprising for its size. Good for emergency situations. Besides, it's handy, small, light and easy to carry around.
I also like the fact that there's 2 ways of turning on the light. 1 by switching the on/off button for sustained light and another is to simply just push to on the light.
Price is good too. Great to have one around you.

Cons: Build quality.
One of the On/Off switch was not working for well for one of the light in my pack of 10. Had to adjust it abit.

Other Thoughts:

Bottomline: Great to have one around given the price. Useful and affordable. Great gift to give away too.

Pros: Really compact little torches,
They are really bright!
Perfect to give away
Handy little switch which I haven't seen on ones in the shops.
So cheap!
Hardly any dimming

Cons: Apparently not water-proof! One rusted up after getting drenched (Fairly water resistant).
Some had to be opened and the leads bent to make them work properly (only like 1 or 2)

Other Thoughts: Really handy to put on all your keyrings to take out with you.
Would be cool if the LEDs came in more variety of colours

Bottomline: Really great product if you want lots of cheap super bright tiny torches!

Pros: -Very very very cheap, my friends wont believe the price I paid for 10.
-Unbelivably strong bright light.
-Unbelivably good built quality (for the outside)
-Great gift for anyone since its so small and cool.
-Long lasting batteries

Cons: -metal ring is not very strong
-"locked on" position is a bit hard to achieve if you are not used to it

Other Thoughts: I gave 9 of mine as gifts, and used the last one's LED to upgrade my mini maglite.

Bottomline: This is one of the products in DX wich i think is very worth the price, having a light in your keychain is very usefull and much better than using your cellphone's screen as a light.
