i mean calculate all the time you will be unscrewing and screwing, the time will add up vs magnets which is instant open, eventually it will pay itself haha
i have the ss version of the bcg
my kannastor and pucks are all aluminum, i believe some parts they didnt put the plastic between the aluminum pieces is where you’re going to grind the aluminum together and get some shaved aluminum, its not a big deal but one reason i got the ss bcg
do you care about shaved aluminum mixed in your flowers ? then yes you will want a SS grinder
is bcg worth it ? depends.. its definitely priced a little high, but as long as you dont drop it, it should last you a lifetime and the only plate you need is probably medium plate, i hardly use coarse...
