I just bought a Youcanic and am very happy with it. Baltimore company, very responsive and helpful when contacted, and no subscription required. I also have a durametric and I haven't compared them directly, but the Youcanic seems to do most things. Used it to calibrate ride height in an airmatic benz, monitor trans temps for proper fill levels, reset can module codes, etc. Emailing reports, printing on my network printer, are nice touches. I would definitely buy it again. I especially like them being local and not a foreign company.
