Decent unit. For a small-time beekeeper like me (2 colonies, 5-15 gallons per season) it's fine. The lid pieces are poorly designed and could be better engineered, as they don't fit snugly or securely. I used my bench grinder to remove about half the material on the plastic lid retainers so they no longer make contact with spinning frames. I wish the unit held more honey before the bottoms of the frames start making contact with the honey, which means you have to stop everything and dump a couple gallons before you can resume spinning. It's great to preserve the comb so the bees don't have as much work to do when I eventually get these back into a hive. I need to put some recessed nuts in my shed floor so I have a more secure unit, but even using it freestanding isn't bad as long as your load is balanced. All in all, a good unit.
