Looks to be pretty much the same as a Coats 640 changer from the late 1970's. Nice to have if you're running a shop, but if you're doing 2 tires per month, a $150 Mike's Racing Products (no affiliation) tire changing stand is fine.
If you notice, the tire changer is $399 + $125 for the pedestal. $399 with the floor mount pedestal would have been attractive to me, but $525 isn't.
The nice thing about this is that you could do your own car tires, too.
