"These work but nothing like as well as the original Mole grips/wrenches. They are uncomfortable to use, with sharp-edged rivet heads. I recommend paying more for quality tools but these are the only self-grips available from Screwfix, sadly."
"I like cheap tools when they can deliver. You can get this set for 8 but it costs 38, because after they have sprung open at key stages or the teeth blurred, the Irwin ones cost a further 30 ;-) Also these are much thicker than Irwin's"
"A very average and flimsy set of grips, possibly useful for light occasional work at home, but useless for trade or heavier work. The grips feel very cheap and parts are slightly loose and occasionally seize up. Save your money overall and buy better ones which is what I'm going to be doing now!"
