I don't think it's the most ergonomic tool but it worked straight away. I've installed two granite sinks with it and it has never overheated. This gave the blade a firm and even power. I had no trouble installing the blade or shield. If you don't do a lot of work that requires an angle grinder, this is an economical solution that works reasonably well for the price. By the way, I've been using a Porter Cable reciprocating saw for repair work for 15 years and it's still fine. I expect this one to be just as reliable given the limited use so far.
