Ground coffee whether unused or the dregs after use do not work for me, nor does grit or the other physical barriers. Growing in pots seems to have some deterent effect on slugs but not snails. One thing that has proved useful against snails has ben by Common Broom plant. They seem to find it irresidtible, and I find lots of them on the plant yet it is robust enough to survive. It has the double benefit of luring them away from the plants they might harm and of course I can collect loads of snails easily and quickly and then destroy them.
