Customer Reviews:

  1. I’ve never used a scroll saw before, and this one was really simple to get into. I’d recommend this to anyone who wants a quick, easy-to-use scroll saw for woodworking projects. The price is nice, and it’s very compact. When not in use, I tucked it beneath my workbench!
  2. In the box, you’ll find a little round tube with a square base. There’s a sticker on it that says it’s for packaging and should be thrown away. Don’t toss it. Wen provides some spare blade clamps, hex wrench, and other tools (additional blade clamps, hex wrench,).
  3. This is a very light saw. I should have been more concerned about the shipping weight. It will bounce around if not secured. The articulated light is of no use. When cutting, it swings all over the place. Because it had a bad motor, I replaced a Delta saw. This isn’t even close to being adequate equipment. This WEN is a great example of how to cut clean and straight. It also comes with a nice work table and may use a wide range of blade types. I’ll most likely give it to a youth group or something like that. It’s not what I had in mind at all.
