"Don't waste your money on this product, quality is awful. The holder lasted me a few weeks (casual use only), then it felt apart. At first, a stopper ring came off, then the hex part, holding a screw bit, sheered off completely!!!"
"was only driving 2 inch screws to fix plasterboard to batons, the holder failed where the hex bit and the holder joins, holder spins whilst screw stays still, snapped in 2 pieces...screwfix replaced it but it happened again...."
"Awesome product, just not up to the job. I've had 4 of these that have been poor and I have given up buying them. The joint between the hex bit and the screwdriver bit fails and the screw stays still while the bit turns round. This used to be a good product, however the engineering standard of manufacture is pants (should that read "are pants") Buy it if you're a DIYer and do not intend to abuse it"
