This was purchased as a replacement for an 18" portable during a kitchen remodel. The flatware tier is AMAZING - I removed the regular basket, since it's just me & I didn't need it. The size is also perfect for me & I run it about every 2-3 days. Large dinner plates do fit, the glassware rack is adjustable, so you can raise it or lower it, as needed - Love that feature.
Installation was straightforward, the controls are very easy to operate, and it gets my dishes spotless! It's also super quiet compared to my portable & the only time you hear it is when it's emptying.
The only small drawback, for me, is the layout of the glassware tier. I don't care for all of the extra tines for bowls & small plates. I use more cups and glasses & would have preferred to have it set up for those. I usually end up with a few cups in the bottom tier, which works fine too. 
Overall, love it & would buy it again in a heartbeat.
