Thoughts/ Feedback about the AC Air Technology tugs?

[TimRF79]

Does anyone here have any experience with the tugs from Ac Air Technology?
Thinking about buying a T1 for my Bellanca Viking, but sure would like to get some user experience

I converted a Hydro-stat riding mower for a tug. Added pintel hitch front and back, made tow bar. Total cost $400.
