Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

- Work very well
- Useful to play joke or to surprise your friend
- It has already the battery in the pen but there are also another set of battery in the package
- It cost less than 2 dollar!
- Full made of plastic
- Poor quality material
- Obviously nonrefillable
I order this mainly to have something to show to my friend but is almost useless. You have to consider that for less than two dollars you have a pen and six batteries. I think i'ts enough to buy it
Cheap and funny.. but useless..
