"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."
"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."
"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."
