They work great. They're very easy to use and set up, but see the next tip. TIP: When using these clips, they will open quickly if you hold the knurled end in each hand and twist them with both hands at the same time. You have probably already used your wooden "big brothersโ to clamp wood. They are slightly different and have a simpler design. You will notice that one of the threaded bolts is floating freely. This confused me a little until I remembered how to regulate their Big Brothers. Twist them together. I found them to be tightly clamped. They are also crafted to fit well together. YES SIR. I would recommend them, especially for the price.
