Zero experience with that, but does seem like a Proto-type, if you will. I'd trust it for general use but not if my job depended on it.
I have problems with digital torque wrenches and simply like click type still. Even the high end ones beep and give a haptic feedback, but still seems to have some reset method that is cumbersome. I also like to see reverse torque, but I wouldn't expect that for $70
Those are me problems, I'd buy it!
