Overall a very good buy and they generally work well. They are quick to set up and I like the fact that they are lightweight and hold their shape. There is limited throat depth so they only work for edge clamping, but I think they are worth having around.

I make several furniture pieces and i use these for gluing up large pieces it works great. strong and since its a aluminium tube its possible to be used as a straight cutting guide when cutting with a circular saw. Own several sizes they work great. price i paid for them was about 8-9 bucks on sale. well worth it. might go back and get a few more.
