I have the tall Porlex Grinder and wish it has some rubber or indentations on the bottom canister as you can get hand ache when grinding for enough for a couple of cups. I now tend to place in on a rubber mat on the worktop.
Great bit of kit and makes a difference in my honest opinion.

Would a Porlex Rubber Sleeve (or two) help? Or else some self-amalgamating tape?
