You will miss out on a few "advanced" features, but it washes dishes really well. I read the manual before I bought it, and I got the performance I expected. I would have preferred to have access to a rinse cycle and a cleaning mode, but I don't need them. It definitely gets my dishes much cleaner than the old failing one I replaced, and I have no complaints so far about its performance.
A few more notes while I'm here:
Yes, partially unscrew the front legs with a wrench before you put it in place. They are too tight. Partially adjust the rear leg before you put it in too. The diagram is confusing and may not adjust the leg in the direction you think it will. I wonder if this is what happened to Jeff.
The dishwasher apparently will refuse to connect to a Wifi network without a password. For mostly philosophical reasons I don't want to add a password to my network, and this is part of the reason I haven't connected it.
Note that the Costco version (at least in my area) is a subtly different model that does not include the automatic door opening "Auto Air" feature. Since this is one of the best features of this model, you should not buy it from Costco unless you verify it comes with this.
The "touchless" buttons are annoying. It frequently beeps and comes to life when I'm just trying to open the door. The interface as a whole isn't great, and I sometimes worry it's not set correctly. But once you figure it out, it will wash your dishes quietly and effectively.
