Has anyone bought from laserpointerpro.com ?

Just wondering what the REAL output is for their 532nm lasers, I don't believe them

Green Laser Pointers: Green Laser Pointer Pen | Laserpointerpro

EDIT Crap, I should have searched first, they scam their power levels.

Junk, waste of money. I have indeed bought from them and I have thrown my money down the drain.
