Horrible seller
The product was used and damaged. It did not work whatsoever. We had to pay our electrician ALL day to try and get this equipment running just to find out it was a bad piece of equipment. Amazon will refund us for the bad product but no one can refund us for our electrical bill which is around $400. We are out a ton of money; I would not buy ANYTHING From this seller!

So far so good. Saved hundreds $
Really disliked the rubber wire keepers at the bottom of the box I had to fabricate something more secure. The electronics seem to be working well It's doing what I bought it for. Decided to take a chance and save hundreds of dollars on an American brand named VFD that is most likely also made in China. The instructions and wiring diagrams are not half bad. No VFD is easy to program and install but if you stick with it and watch a few you tube videos you'll get the hang of it. I'll let you know how it goes long term after it's been in service for awhile. Have not run it under load yet. I bought the 5HP version to soft start a 3HP motor from a on off switch, nothing too complex, although the box is complex enough to set up and program any which you can think of.

Wiring instructions were different in instructions. The instructions on Amazon were correct
Like the easy operation. Programing was difficult. Used on metal lathe.

For the money you can’t beat this VFD
Great VFD, the only thing I dislike is that the cooling fan is always on which is annoying but livable. It would be five stars if the fan only kicked on when the unit was heating up.

How to set up, and direction on error codes
Easy install but problem making the saw operate with no directions for error codes, would not recommend this item.
