Review on 🔌 SE 15 Amp Electronic Variable Speed Controller by Edgar Gomez

I bought this unit to slow down a very inexpensive sewing machine I just bought for my grandchildren. I am an avid seamstress and would like to introduce them (up to age 7) to sewing without using my expensive sewing machine. When I got this controller the instructions said it couldn't be used with a brushless motor - I had no idea what that was so I called the sewing machine shop who had a service department. He was looking for a motor for me and said my sewing machine was a brush motor so I used it. I can only use a certain speed on it but it slows down the sewing machine and makes me breathe a little easier knowing this device has made the machine safer for my grandkids. If I had a little more control over the speed I would give this device 5 stars instead of 4.
