Was looking on the B&Q site for some timber bits and this popped up. Seems a decent price, and handy too. Tempted to pick 1 up to replace mine which isn't too reliable now.
You can also R&C online and get quidco for it too.
The button, for some reason, takes you to a completely different product, even though I copied and pasted the link. The product code is 0000003448991.
