it was cheap

Not got great reviews here but to be fair, I can only write from my personal experience, it was the cheapest sds in the shop, it was on sale, I never expected it to be the bees knees. a couple of bits have fallen off mine (the red plastic grease well cover thing on top that seems designed to strip its threads and fail) but it's stripped the render off a three storey farm house and is still going strong. I might have just got lucky, the problem with cheap imports is the hit and miss quality of the manufacturing, the manufacturers only make stuff to just fill the quality of the order they're given, with the acceptable number of sub-standard parts seeming to correlate nicely with distance from point of sale! It does the job. If i was using it professionally I'd probably have gone for a better quality make but if you're just wanting it for one big job or general pottering around the place style diy then this is fine. If you want something that will last a lifetime then don't buy this. You won't be passing it on to your grandkids, but welcome to the beauty of built in obsolescence and the consumer society.
