Benefits are small except for price and weight. Although it can cut, since the backlash is large in the motor shaft and the drive part, rotation stops as soon as a slight load is applied. Even when I start up, it will start with a bad feeling like "Queen." It can not be cut with a single lowering, and it is necessary to raise and lower while keeping the rotation many times. The material stopper bracket is also insufficient in strength, so even if it is fixed, the material is shifted from the bracket when cutting. I tried to weld the steel plate to the bracket. If you can afford, we recommend a better one. It is something that really cuts out a little thing. Even for DIY is a bit strict. By the way the cover is rattled.
