I find copper tape works well. Bear in mind, slugs will enter pots through the bottom or may already be in the compost. If a nearby pot plant has leaves that touch your protected hosta one slugs/snails can bridge across. Ironically pots can be worse than the open ground. ,slugs like to breed/hide/whatever under pots...turn over your pots and chances are many of them will have little slugs there.
wiping the tape occasionally helps I think....a layer of dust may reduce its effectiveness.
re Google reviews...they're fun aren't they? I dismiss the extreme views and look at the average.
prob the best solution is to use tape and nematodes.
So far I manage to grow damage free hostas...I posted a couple last year.......in pots and in the ground. My regime is checking at night with a torch and salt solution. Allowing hostas to flower too is a great attraction for slugs I think so the best foliage varieties have their flower stalks removed. Otherwise at flowering time be more vigilant.
