Easy instructions to follow
Too early to say bu5 looks promising with very easy-to-follow instructions……first coarse grit pebbles turning as we speak

Box looked a mess, but contents fine.
Looked like it had taken a bashing during transit which is a shame as it's a gift. Bought with £10 off, so a good buy.

Poor quality
Too many tiny bits of rock that tumble away to crumbs. Not worth the money
