I've blown through a couple corded and cordless Dremels. Name brand, and off-brand. I still keep going back to the Dremel brand. Outstanding service, and they've always held up better than anything else I've tried. I'm happy with the lifespan I get for the price.
I tend to work power tools very hard. I can't really afford anything above consumer-grade yet, and using consumer tools in contractor applications does mean faster failure than most people get. I've burned out a few DeWalt drills, Skil jig and circular saws, soldering irons, just about everything. It happens. On the plus side, I have experience with the durability and shortcomings of quite a range of brands. When I say I like something, I've had a lot of experience with it, and despite a few failures, I feel it stacks up well against other options.
Is this Clarke a UK only brand? I've not heard of it.
