Takes a little Tim to set up but works great

I've only used them lightly and maybe I haven't the skill to use them for any kind of finishing details. Also not sure if they'll handle heavier use. I found them a bit tricky to set up with no instructions but if you manage to get your fences aligned and find the right stock they work well enough.

This product advertises an American company from Houston TX. But this is not a company, just a mail service box. I take offense having served with the Air Force , that this Chinese company is trying to convince you that you are buying from an American company. Also, this product is not simple to set up, as the instructions suggest. Have plenty of scrap wood to do test runs , over and over ...... set your fence and gauge your depth carefully.

This picture tells the story.
