Got it a few weeks ago. Huge improvement on our 40 year old dishwasher.
The main rack doesn't roll smoothly back into the machine (just the way the track is designed), so it takes a bit of force and twisting to push it back in.  This concerns me for longevity of the back wheels. Other than that everything works as expected, and rack layout is working well for us.
There's probably a better designed alternative at the price point, just because of that one design flaw.
