"I bought a pair of these last year and am well satisfied with the build quality. For those of you who wonder if this cheap product is any good, I can only speak as I find. I have used these clamps to straighten bowed 100mm half round poles as they are being fitted to 100x47mm stud frame. The pressure that I have needed to exert on some of the poles has been excessive to the point where the clamps bite into the wood. To date they are still as good as the day I purchased them"
"This clamp is as good as the much more expensive ones and much better than the cheap aluminium ones. I use mine for squesing toether several planks dowel jointed and find I can put plenty of pressure on."
"I bought 4 of the 24 inch clamps. I was running out of clamps when making several oak kitchen doors. Firstly the bad points. The jaws do not stay square especially the movable jaw. The location pin drops out. But I have this in more expensive ones. The tommy bar is short and of a small diameter. On the plus side. They are solid and rigid in use. The screw thread runs freely. Quick to adjust and the location pin is attached to the clamp by a wire. So when it falls out, which it will, no searching on your knees. For the price I have seen far worse."
"These are much better than the cheap Ally cramps, and a fair bit cheaper than Irwin. So on balance they are a good buy, maybe not as smooth, but for the price, and considering I don't use them that often they are great."
"Should not expect too much for the money but this product is poorly finished. The heads are very uneven and pieces of wood used as protection tend to slide out because of unevenness. The retaining toggle falls out at the slightest angle. You have to be careful on tightening the clamp: the loose fit of the moving head causes it to move from alignment. With these points in mind, the clamp will do its job but if I had borrowed one prior to buying, I would not have purchased."
"I bought a pair of 24" 29861 clamps on 21Aug08. Used them, or tried to use them, first time on 09Aug09, so well out of warranty. The screw threads and the boss through which the thread operates seem to be made of a very soft metal. The result is that, as the screw is turned, it rubs and wears, even when no load is being applied and even after being lubricated. I surmise that swarf builds up in the boss and the result is that the thread jams in the boss and extreme force is needed to free it. What this product does NOT do is to, "... apply force quickly and smoothly". I would happy to drop them off at my local branch for examination by your Quality Department. I regret to say that this is the worst performing tool I have ever bought from Screwfix!"
"Very disappointed with this product. Attempted to assemble a simple finger jointed box using these clamps, but had to resort to block of wood and mallet instead. The screw on the clamp head binds, and tommy bar has no strength at all. It looks like a Record clamp, is cheaper than a Record clamp, but don't bother buying unless you want it for an ornament."
