This is my first grinder so I have no comparison but it meets all my expectations. You have to buy a cartridge. I give it 4 stars because I find the speed is too high and it loses too much power when slowing down. I'm changing my rating from 4 stars to 1 because it broke yesterday. The part got stuck and instead of just stopping, the fuse blew. If the fuse is replaced and restarted, it will blow immediately. I'm abroad, so I don't even dream of a supplier's help. I had to drag him across town looking for an electronics engineer. I still don't know if they can fix it.
