Tech support was my top priority and was very good. Thanks for that ! I wouldn't need it but it was still great and more than expected! I've had very few minor issues that were easy to fix, but that's normal. I really like the induction motor and accompanying VFD as it is very smooth and controllable. Magnetic ON/OFF and speed control unit can be placed anywhere (I'm right-handed :-). It comes with a 1-1/4" stem thread, which some people don't like, but I like the stronger stem. Nothing bad I can say except that the letter "W" fell off, it's ok, now it says "ahuda" :-) which means "friendship".
