ODELENWA Double Handle 90° Right Angle Clamp/Corner Clamp with Aluminum Alloy Body, Upgrade Steel Nut for Welding, Quick-Jaw Corner Clamp for Wood-working, Photo Framing

I've only had it for a couple of weeks but I've used it on a couple projects. Every time it holds square and holds tight. Workmanship seems pretty solid/durable.

I used it over the weekend to build a storage rack. It works well.

Very well made. Holds perfect 90 degree angles for welding.

So far so good. I used this to clamp together my pieces for a draw I made. I purchased it for the larger 2x4 that I will be joining together for another project but for smaller pieces it works well. I am looking for a smaller corner clamp for smaller wood pieces just for easier use of space and ability to be more agile when clamping. I do like the quick release to save too much twisting motion on my wrists.Update: I had to down grade to 2 stars. I used this today after several uses and found the connection from the rod that attached to the block had broken off. After looking at the end it appears to be poorly made. The metal seems to have snapped off from the block housing. I bought only one to see of this type of clamp would work in my projects. I am still looking for a better clamping tool to put 2x4 and other material.2nd Update: Tried to hold a mitered 2x4 but I found the champs design open up the joined miter ends when tightened.

It's a good clamp. I would of liked it better and gave it 5 starts if it would hold a 2×4 flat. It's like a half inch shy.

Works as advertised. Used it to construct a chicken coop. It made lining up all of the frame pieces very easy.

Strong and accurate and works with 2x4 lumber.

I was surprised that this clamp was so poor after all the positive reviews. There is nothing holding the threaded handles into the clamps themselves, so if you turn the handle to open the clamp, the handle just pulls out of it. Definitely a missing piece where the handle connects to the clamp. The clamps themselves don't open anyway because the screws in the back plate were put in way too tight. It can be modified to work but it is totally useless the way it arrived.
