Looks great on my counter, lovely design, looks solid, sturdy, industrial. So far great.
Two reasons for the missing stars:
A) mine came slightly scratched, not bad enough to call SAI, complain about it and then have to go through the hassle of returning it to get a new one, but I would have liked to get a pristine block, I didn't. Better QC would have flagged this item and could have been repolished before shipping it to me.
B) the tamping support is a bit flimsy, if you press hard enough it actually moves/bends/buckles a bit, it feels you are going to break it. I somehow mitigated it by adding some rubber support underneath (between the bucket and the counter), but SAI should redesign it, this needs to withstand tamping force.
On the looks 5 star, add the feel while tamping and comes down to 4, the scratch QC overlooked makes it 3 star. If you are lucky not to get a scratched station, you can expect a 4-star item.
