Review on 🔧 Optimized Positioning for Aluminium Woodworking Carpenter Clamping by Amicz Kakaruk

There really is only one measure of 'quality' for a product like this and that should be 90 degrees. I bought two sets - four in total, and three of the four were at 90 degrees, but one was far from it. It sucks. I bought these because they come in handy as a set of four for framing and similar projects. An absence makes the whole set less useful. They're not incredibly expensive, so it's tempting to buy another one, but I don't want to reward poor results. :(
