The tire changer itself is nice, especially with the extensions for the legs, it puts it up at a really nice height to work on things without bending over my old back too much. I found the bead breaker teeth to be rather extreme, and I had to be careful or they would damage the sidewall of my tire.
I'd like to see a clamp tool made that works like a bead Buddy & can be clamped on the bottom of the rim, and then be used to force the top bead down into the drop center of the rim.
