This seems to be a good, cheaper alternative to a dremel in that the drill will fit official Dremel accessories and bits, but it comes with 163 pieces of it's own fittings anyway.
Reviews of it on ebuyer are all promising with an average of 8.6 out of 10 (based on 183 reviews). And for under £20 delivered it seems to be worth a shot!
I think this deal has been posted in the past where it dropped down to £14.99 but that expired quite a while ago. This is a good price compared to the usual cost of an official Dremel. But like I say, for odd jobs around the house and fixing up rust etc on my motorbike, think it will do the job nicely!
