Pros: Gives a nice shock that leaves you tingly for a while.
Has a warning lable on it even!
Good quality laser. and shocker unit.
I ordered 2 and both were black nice colour :)

Cons: The batteries look hard to change but ill figure it out.
No other cons except button is kinda loose no biggy...

Other Thoughts: Best shocking joke that people are likly to use.
( most believe able )
Remember that the button near the tip of the laser gives the shock because its easy to forget.

Bottomline: Buy one if you like to watch people get zapped or simply want a laser...

Pros: It is simple to use and even comes with instructions on the back.
It is cheap when you think tehy have to ship it around the world.
You get 2 packs of 10 which i did.

Cons: Candle smoke is smelly (but all candles are)
When you blow out and they relight it makes lots of smoke so if you keep doing this to many of them it will be LOTS of dirty smoke.
Other wise very good product!

Other Thoughts: Great item for any occasion.
You can use with only 1 it just works a little better with more.

Bottomline: Buy them becuase there always is an occasion that your could use them!
