I bought this tool to remove grout between bathroom tiles, using the appropriate segment saw blade. The tool stopped working within a couple of minutes, so I switched the mains suppy off and left it for a few minutes. It was then operational so I figured it may have over-heated and got on with the job, periodically switching it off to permit cooling. After about an hour, it failed agaon but this time for good. Opening it up, I was impressed by the quality of the motor within. Testing showed that the fault was on the speed regulator printed circuit board but nothing obvious (like the triac). Having seen some other online reviews, like on this webpage, indicates possibly (in my opinion) either a poorly designed circuit or there is a poor quality component on it. If only it had not failed, I would be singing its praises as a useful addition to those who use power tools.
