Any Butterfly vario users out there care to share their experiences?

whether the A/H is stable and usable? (Not too bothered about the

I have a Butterfly vario. Wind is instantaneous. Very reliable. Hardware is best in the business. It is a real eye openner to see the difference in the actual airmass behavior and the inertia of the glider. Bruno has some good videos of this behavior. A pilot can learn a lot with this vario.
