These clamps are superior to the old angle clamps I have used in my woodworking hobby for many years. The old clamps were difficult to align and I was never guaranteed a 90 degree fit. Not only are these clamps good in terms of ease of use and accuracy, but they hold up to similar resin/plastic products that I've read about breaking when clamped. The price is definitely a bit more than I wanted to spend on one clamp (I bought 2). Having used them I will now invest more and hope I never have to buy a set again. I've read complaints about red paint transfer, and while I've seen a few of these, they were minimal and I was able to sand them off right away. I'm glad I bought these and not the plastic versions which are cheaper. It is also nice that you can easily combine two different strengths. Overall I am very satisfied and would definitely recommend them to anyone who needs good woodworking corner clamps.
