It came with a dent, but it doesn’t seem to affect anything other than the appearance. 
I am surprised at how well it cleans for a counter top unit. I put dishes that are several days old and unrinsed and have never had one come out with residue left on it. I run everything on the potspan cycle and it takes about 90 minutes but those dishespans come out clean every time. The manual doesn’t recommend using the dishwashing pods but initially that’s all I could find. Since I run the dishes on the LONG potspans cycle I’ve never had a problem with the pod not melting down like it should. I also use the rinse solution recommended in the manual. 
So far I have observed no leaks at the back where the hoses all connect. 
For its size and limitations compared to full size I think it does an excellent job. 
At this point I am pretty favorably inclined towards this counter top unit. It definitely exceeded my expectations. I would recommend this unit. 
FYI replacement parts can be found online
