I have been on one a couple of times, and fairly recently took my buddies car on one. They eliminate tire slippage issues over the Dynojet. They also can hold the car (up to their torque rating)at a certain rpm under full throttle which is great for getting some loaded numbers. They do have a lower power limit than the 248 Dynojet as my yellow car kept shutting it off (too much torque). This assumes that they're using the $65K model; they also make one that's nearly $100K that handles more power/torque but I've never seen a shop use that one.

Overall, a neat deal that eliminates having a pit or lift for the rollers, takes up very little room in the shop, and can load a car better than a Dynojet.
