I have the version 1 truer, bought it 18 months ago. Very happy with it!
Paid $235 for it, 1/8th & 1/10th arbor and shipping from Dinbal. Supplied cutting bits worked well but opted for the Hudy carbide. It changed the calibration of the diameter size but a scribe mark with the dremel cutting wheel and a dab of white paint got me pretty accurate. Strong motor cuts 3 or 4 mm on a single pass with no motor bog, powered by a gel-cell battery.
I like the addition of the onboard battery option and the tire dust tray! I haven't used the tire edge device because I only cut 1/8th and they are more for 1/10 size tires. What would be cool is if they were made with a permanent carbide surface instead of the stick-on 80 grit sand paper strips.
