The PenSimple is a deceptive little product that should (most likely) be avoided. It’s advertised as an electric herb grinder — but it’s not. The actual grinder portion of the PenSimple is quite poor and requires hand-holding throughout the whole process. You know the deal: constantly having to check if it’s cleared yet, the need for a stick to poke stubborn weed bits through the holes, inconsistent grind consistency. You get it.

The real allure of the PenSimple is its auto dispensing ability. Rather than automatically grind the bud, instead it’s designed to propel weed out of a nozzle. I say “designed to”, because it doesn’t actually work that well. Read the reviews on Amazon, and check out the Youtube reviews, most of them are poor. The only real scenario in which you should consider this device is for tobacco, or if your bud is super dry and therefore it’ll grind and dispense easier.
