"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."
"Bought these a few months ago as an attempt to build up my clamp collection which is very small, however I wanted to use these for a bit before reviewing.
The price is great for 2 in a pack and work as you would expect F-Clamps or any other clamp.
However there are a couple of "features" that are not massive problems but worth pointing out. There is a plastic cover over the top clamp holder, this falls off immediately and will not stay on. I tried some wood glue to hold it in place but this was not good enough. I have decided to remove these completely as they are not a major thing
However the bottom clamp holder also falls off its ball holder all the time. I have ended up using my mole grips to pinch them at the bottom slightly and this allows them to still move freely but stops them falling off.
I think these clamps are great value for money and despite these very small issues I highly recommend them to anyone... Maybe just be realistic on what you get for your money."
"These clamps do the business for most jobs, but for precise work the "forgesteel" ones at only slightly more money are very much better. Alignment of these is a bit more sloppy than the alternatives, and the tightening thread much less smooth so more difficult to equalise pressures between clamps. However, I'll still keep on using these for rough work, just not buy more ."
"What can I say... terrible clamps. As others have stated, the very least you'd expect them to do is... clamp. One of the pair just about did, as long as I was helping force it into the (very shallow) locating notches, and the other just wouldn't grip at all.
Got a refund and won't be buying the cheapest anymore!"
"I'm staggered by the good reviews of these clamps - so much so that I've signed up with Screwfix JUST so I can post a review about how unspeakably useless and infuriatingly terrible this absolute *junk* is. I cannot begin to imagine what went through the minds of either the designer, the workers in the factory, or indeed the product buyer at Screwfix in that any of them thought that these pieces of utter rubbish would be in any way sucessful at clamping anything at all. It's true that you get what you pay for but regardless of how little I paid for them, I paid for CLAMPS so it's only reasonable to assume that at the very least they would function at clamping things. But no.
The design itself is so obviously flawed in that it relies on (poor, practically non-existent) friction in the serated edge to stop the moveable part of the clamp moving up the serated edge when you tighten the screw - which it fails spectacularly at. This means that as soon as you try and tighten the screw, instead of providing more (or indeed, any) clamping force between the jaws, it simply moves up the serated edge, often then falling off the two things you're trying to clamp.
The time, energy, and patience that I've wasted on these pitiful pieces of rubbish borders on offensive, and frankly I get angry even looking at them, in just how ultimately useless they are. Why did the factory even bother making them, and why on earth did Screwfix even bother buying them in? Save the frustration and dispair I've had to experience by avoiding like the plague. For the sake of the sanity of you and those around you, DO NOT BUY THEM."
