Corner Clamps for Woodworking - Right Angle for Woodworking 4 Pack 5.5“x 5.5” Aluminum Alloy 90 Degree Clamp Corner Clamp Tools and Equipment L Square Aluminum Angle Clamp Tool

Very nice no difference in the high priced ones

This is a very good set of corners set. I’m buying one set a month until I have enough for my shop.

Good idea on paper, but in reality these gizmos are quite awkward to set up and corners never quite line up perfectly. Takes a long time to adjust. You'd almost need two more hands. Also, the screw thingy binds a lot. Good, but is it worth nearly $40? I don't think so. I wouldn't buy again.

Great set of clamps. Well made and very useful for your projects.

Several people commented that this worked on a 1"x4". Clamps only good for a 2 1/2" board.

The clamps work, but there are so many situations where you'd think they would be useful, but they are hard to use. If you use them at the bottom of a project, you have to ensure that each clamp is set up the same (so the project has the same elevation). And they can only be used when the place where the boards join are at the same size (if you try to join a 24" x 24" piece of plywood to a 19" by 27" piece, the clamps are useful only at the end where the boards come together at a 90° and flush (so at one edge, and not the other). Also, since each clamp involves multiple parts, it is easy to need more than 2 hands to set things up right -- I found a different set of right-angle clamps with all the pieces integrated was far easier to use. That said, there were some situations where these clamps were perfect -- just the right tool. But those situations are less common than I would have thought.
