Pretty good, I got the spherical pocket bubbler and hemp cannabis grinder. Its kinda hard to get the **** out of the grinder by hand but putting it on a plate or bowl fixes that. The pocket bubbler has a small 10mm bowl but definitely gets the job done. Would recommend getting a pipe screen first so you dont lose bits of **** in the water.

Amazing product love it

It grinds very well! It does seem to get a little sticky on the spin after a couple uses but still easy to use.
