I got one of these used several months ago and it works great. It has no trouble getting onto and over the thick doormats we have, unlike previous ones I've tried.
My one complaint is that it requires your wifi network to be visible. Most people keep their visible, so this won't be a problem, but after having my wifi hijacked a few years ago, I keep mine invisible. The Deebot works fine, following its schedule and area restrictions even when offline, but if I want to change something, I have to make my network visible, reconnect the Deebot, make the change, then make my network invisible again, which is inconvenient.
Also the suction on the self-emptying base isn't strong enough to clear clay cat litter out of the robot, so I still have to empty it out manually every so often. It sucks the other stuff out just fine, though.
