As of today there are no Medit Owned service center in the US as told to me. A number of resellers have limited ability to service Medit scanners but there are loaners. There are some resellers doing service work for other Medit resellers. Can't imagine any Medit reseller today not having a loaner since its rare that Medit scanners breakdown. Over the years I've bought scanners from 3 different resellers and all with loaners if needed which I didn't need.
No clue the average life of lab scanners but I can say newer faster more accurate scanners come out every several years. My Medit Hybrid bought in Dec 2016 was outdated less than 6 months after buying when the much faster T500 release. In late 2020 newer Medit T Series scanners were released, T310, T510, and T710 scanner. So my Medit Hybrid that's still a great scanner in todays times and with the ability to scan impressions is now 2 generations old in 3 yrs of my ownership.
My point in my posts, lab scanners don't last forever and not meant to with ever growing improved technology. Look at how fast IOS scanners are improving in just a few short years. The Medit i500 IOS is probably the best first generation IOS scanner ever made.
Should you buy DOF or Medit, both have been top of the pack scanners and have been since being released. Not aware of what year the DOF Freedom HD was released, bet DOF has a newer model in the works ? When I ordered my Hybrid in Nov 2016 the other choice I had was the Freedom HD, but maybe I'm wrong in the model name ?
