Not too bad, but a little wobbly
This clamp is pretty good, but maybe a little wobbly. We use it with our welding setups, and it works well for securing items tightly. The only thing that I think is a bit sub-par is that it's sort of wobbly until you get your pieces arranged exactly how you want them and are able to set the clamp. I would buy it again, but I just wish that it was built a little more tightly.

Works great
It’s not heavy duty by no means but if your gentle with it it works great . It hold your metal to a perfect 90 for welding .

strong enough to hold pipe to sucker rod
welding a pipe fence alone and this is as good as having a helper

Works but kind of cheap and small
Does what it's supposed too but not very heavy duty. Disappointed in the quality.

Great tool, perfect for what I.
Just what I needed. Glad I spent the extra couple bucks to get a solid quality tool. 👍🏼If you buy the right tool the first time you won’t have to buy it again

Prácticas e utiles
Relación precio y calidad creo que están correctas. Les falta resistencia al material pero cumplen con su función. No demando más por lo que no pague. Las recomiendo para trabajos caseros.

It was is a good clamp I just wish it was a thicker material.
It's a good tool for corners but I wish the clamp material was thicker to last even longer.
