The spider pen looks like any other regular pen.
Works like ITR but you can have better control of the reeling.
Silent motor as advertised and refill is easy.
Used it many times and the thread doesn't break easily.
Tension of the thread is pretty tight too.
Change of battery is easy and there is a compartment to hold a spare spool.


Whoever have owns a pen can PM me we can discuss how to put the pen into greater use.
For those who are thinking of buying one...can PM me to get more details
