"I bought 18 of these twin sets of F Cramps for a project for St Gemma's Hospice Windermere Row to fasten rudders to rowing boats. They may be cheap, which is appealing, but they do the job admirably. I bought 12 sets in 2014 and they are still doing the job."
"Bought them to clamp A jig to a door, just the right size so they don't get in my way or the router. Wanted something a bit firmer to grip than a trigger clamp and these do the job. The clamp slides down the shaft then locks into place on a serrated edge. Then you can treat the handle to apply clamping pressure. All metal apart from the red handle. Cheaper than a lot of makes but would buy these again and getting some larger ones for bigger jobs"
"Although I haven't used them yet, and just for the look and feel they seem good enough for any small job, they are good clamps, small enough to fit in my tool box, and to do that wee jobs around the house and a exceptional price."
"Not the best clamp, but cheap and cheerful, and one of those tools you'll wonder how you lived without. No matter how many you have, you can always use a few more. I'd rather have ten of these than just one expensive clamp."
"They do the job at a cheap price. If you're not paying attention the bottom section does not always engage into the spine, so needs a little shifting of the bottom piece before winding up. If i'm honest i'm not certain if a slightly more expensive version will be less susceptible to this issue."
I have to write and say the ones I have work fine.
Over the years I've accumulated a great many clamps of all types. There are occasions, particularly when building boats, when you just need a very large number of clamps applying moderate pressure (so as not to squeeze out the glue.) These do that job.
Where necessary I intersperse them with other heavy duty clamps.
I have about 40 of these. That represents a saving of around £80 over the excellent Forge Steel clamps next up in price. Money I was able to spend on other tools (like a few more expensive clamps as well.)
In the past seven years I've owned these clamps only one has come apart. All the rest continue to function, albeit without the silly plastic cap which, as others have said, is a waste of time.
Maybe I've been lucky. Maybe quality has got worse. Maybe I'm just using them in ways that suit their abilities. I can only report these clamps continue to serve me well."
