My advice is to stick with clamp models which have been in production for years, and buy them from known and reputable manufacturers.
When I was younger, I bought all different kinds of low cost clamps from a bunch of screwball manufacturers. Most of them didn’t work well.
I started to make more money and have more discretionary money. I started buying known styles of clamps from known manufacturers. They work, and are easy to use. The ones I had been buying werent inexpensive. They were cheap, as in ”of poor quality and utility, thus low in cost”. And, in the end I spent far more money, because I have replaced all of them
It bothers me a bit when folks use cheap to mean inexpensive, so that now folks think they are synonyms. Cheap, means, “of poor quality, and utility, thus low in cost”.
