Review on 🔧 Aluminium Clamping Woodworking Carpenter: Enhanced Positioning for Precision Work by Stephen Cernatescu

They work, are very sturdy and all 4 are square or pretty close. With a digital meter, they were all between 89.7 and 90.1 degrees. Still, I wish they were cheaper since they're just very basic CNC aluminum and aren't hard to square. Measurement grid marks are used somewhat, so maybe not worrying about etching would help save money? In any case, despite the higher than usual cost, it does its job and does it well. They are strong and don't bend even if I apply enough clamping force to the slot area. If you take care of them, they will accompany you for life.
