Thanks to my knowledge gained in practice, I can confidently say that this product is not worth the money. The adjustable design is so flimsy that it fails to hold material securely in place, making it completely useless for any serious woodworking or welding projects. While it's lightweight, it's also made of cheap aluminum that easily bends or breaks under even the slightest pressure. The only pro is that it's affordable, but you'll end up wasting your money on a tool that does nothing of value.
