Defective Gansulin Pen?

[iMemphis]

@randy

So I purchased the gansulin pin about 1-2 weeks ago and everything was working fine. Tonight, I set the units to 40u, pinned my rat, it slowly got to 20u...... then it just simply stopped. I keep pressing it, nothing happens. Could it be defective? And if it is, does the pens have a warranty/exchange through you guys since I purchased from you?

Thanks

What size needle? What compound? is the stopper in the cartridge crooked? have you tried it with the cartridge warm?

This is likely one of those and not a broken gansulin. even ive had this happen a few times.
