After i put it to the test during my woodworking projects, I can say that this aluminum positioning device is truly excellent. It firmly holds the wood in place so I could work with precision. The device is also made with high-quality materials that ensure durability even after constant use .My only concern is that it might be a bit heavy to move around but it's a minor issue. This is a must-have tool for any professional woodworker and a great investment for any workshop. Definitely worth the purchase!
