Pros: The pens are pretty cheap for what you're getting. It's very fun to shock your friends and most usually fall for it. Great part is, it also functions as a working pen. Not only is that a good thing for when the charge runs out, it's a good way of making people completely unsuspecting because the pen works.

Cons: The pens are really cheaply made. My brother and I got a few of them and the quality varied. One or two of them fell apart and we had to put them back together with a glue gun.
It can also be hard to write with them. The writing comes out pretty thin and light or sometimes it gives out altogether.

Other Thoughts: Don't try using them on friends or people with heart conditions. Apparently that's bad. Hahaha
No, seriously. I got one to shock one of my friends and a teacher of mine, but my friend turned out to have some kind of heart condition and she recognized the pen instantly and told me about it. The teacher I was planning on shocking for stealing my pencils constantly, but I realized that would probably be a bad idea because he's pretty old and who knows what kind of conditions he has. I dunno. Maybe I'm paranoid.

Bottomline: The quality may be cheap, but so is the price. It does what it's supposed to do and it's really fun to shock your friends (provided they have a sense of humor). For $2 why not? Get one!

Pros: Its a nice gadget for shocking people,and it doesnt realy hearts.
It is also a working pen so you can write things and then shock your friend haha.

Cons: The quality isnt so great..its made of a cheap plastic.
the shock could have been more powerfull.
i've opened it, and it's cheap quality build but it works fine so..

Other Thoughts: Well,i just got it and i must say,it works just fine.
i've been looking for something that whould actually surprise my friends and shock them,
and i think i've just found the perfect thing.
im afraid that it will breake but its just 2$ so..thats a Relief.

Bottomline: If you are short in money or looking for a cheap thing for shocking your friends- You should get this.

Pros: Gives a nice shock but not too extreme
Looks like a normal pen which makes it easy to trick people with.
Was fun while it lasted. Had some great laughs and really surprised a lot of people.
Be careful who you give it to, one person threw it right back at me out of surprise

Cons: A little bulky and oversized
Batteries were held in place with masking tape and the insides were rusted and falling apart
Stopped working shortly after i got it, maybe 10 shocks
Feels like cheap plastic

Other Thoughts:

Bottomline: Not bad for a quick practical joke but don't expect it to be a long time. Short battery life and bad build quality make it a loser in my books.

Pros: Looks like a pen
Point of the Pen comes out to make it look real
Shocks are powerful and really funny
Price is Good For the pen

Cons: Cheap build leads to easy breaks from dropping throwing etc
The battery life is short but i guess you could always buy more right here at deal extreme
May be able to tell its a trap but the cheap metal top of the pen

Other Thoughts: Make sure you use it on people who have a sense of humor some people cannot take a joke.

Bottomline: A great little gadget to shock and amuse you friends and family Great in School and Office settings
