Great clamp to help you weld.
Great durable tool to hold your metal for an accurate weld. Much better price than local welding suppliers. Well made and fast delivery. I would purchase again.

Very small
Leverage handle is very small and it can be a little difficult to get the tool and metal lined up where you want it. It is a nice tool to have though when working with small diameter tube steel only wish I had gotten a bigger clamp.

This a great tool for woodworking. Never been easier to position wood for framing. No complaints - great product. Strong Hand fan for ever.

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.

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

Acquistate due al prezzo di 27€ cadauna, una chiude bene e in linea,mentre l'altra è fuori linea dove ha il foro filettato con barra filettata. Praticamente hanno fatto il filetto storto. Non faccio il reso ma da fastidio sta cosa. Certo che in foto sembrano molto meglio.

調整ボルトにもう少し工夫が欲しいのと、ボルト一緒に回転するので使い方を工夫しないといけない。
