Pros: Works fine. 3 tests passed: first writing left under the intense light, second writing left on the heater/radiator, third writing left in the drawer/locker. No marks left so this can be used for cheating :D
Cons: The push button could be soundless. There could by several color types. The uv flashlight part could be smaller. I'm going to modify it in order to make it as tiny as possible. maybe remove some batteries.
Other Thoughts: This pen can be useful in various way not only for cheating. For example in the night club you can do some stuff like paint something on your clothes or etc...
Bottomline: Nice to have one while being student or schoolchildren. It also can be used for other purposes. It only depends on your fantasy :)
Fun for kids

Pros: Works as described, my sister use it at school to write messages to her friend.
can be used for marking, if someone steals a marked object you can prove its yours. noone would know it's there so they won't remove it.
Cons: doesn't make me waffles, or light my cigarettes. and its letter's here wont count as one of 500.
Other Thoughts: easy to use, cheap, why not just add one and see.
The diode can be taken out and used for diy...
can be used on money too check if they're real.
Bottomline: good product which would cost atleast twice in Norway.
Good thing

Pros: Build-in flashlight. Bright, batteries included. Easy to use. Good for your children. It is cheap, when you want a lot of pieces, you can use BULK RATE coupon. You can use it for detecting wrong money.
Cons: Quite good build quality, but not perfect. Depending on the sun, sometimes you can se written text, but not often.
Other Thoughts: Compared to http://www.dealextreme.com/details.dx/sku.22117: 22117 is thin and better build quality and more batteries. 88 is stronger and cheaper.
Bottomline: Good, cheap. I am very satisfied.
Nice and useful toy

Pros: LED is very bright. (you should use it for recognize good bank notes too). Very cheap and very useful.Can be used to write secret messages. my children loves it.
Cons: not at all, maybe you cannot write normally with it
Other Thoughts: This is a great little pen. In Italy it is not easy to find and the price is much more
not cons at all, maybe you cannot write normally with it you can use only the invisible ink
Bottomline: Have ordered seven more as everyone else who has seen the pen also wants one and for some funny little gift
