I have a 1k, 2K, and 3K (3K not being used right now)... I like them. Cleaning isn't a big deal as they come apart easily for standard cleaning of guard and blades. If you are doing a full teardown and cleaning getting a few of the inner pieces off is a bit tight, but I've done that once in the past year and after I got it apart it didn't need it.
I did have 1 problem where the dual WiFi controller wasn't working one of my gyres, it was erroring out. Support was quick to respond and I just needed to a soft reset on the controller and adjust a few setting back to what I wanted and it was good to go. Only issue I've had with any of these in 1.5+ years.
