Crabink, that's quite a bad generalisation. You can't say a spirit or thunder doesn't tattoo great? They are unadjustable, Also IMO the ego vice is actually the best vice I've used! The plastic was definitely not weak. It grips stainless and plastic amazingly well with no movement. My aluminium vices tend to not grip as well. Especially stainless grips tend to slip on occasions with other vices. It's a real shame if that put you off because the Ego is a great machine.
