Gansulin Auto Research Pen

Awesome delivery and service.

First things first, the pen is pricey and I won't be buying another one lol. That said, it's slick and the dosing mechanism is smooth. Knock $100 off and I'd buy a handful. If you can find it or it's analogs closer to $50 then but it immediately. It surpasses my V2 and V1 easily. I'm looking forward to comparing it to the Gensu2.

Great pen works amazing. Need something that can also push oils
