I have brought 1 of these and they are the worst pollen presses ive ever had i will never buy again i had to screw a screw into 1 of the spacers an use a hammer to grip onto the screw an yank them out because 1 end was solidly stuck an then the spacer got stuck an i had 5g of pollen stuck in there absolutely pathetic press please do not purchase thos from anywhere. Spend the money on a decent 1
