This concrete saw was a total surprise. I have owned professional model concrete saws and really didn't expect much, but the saw did a brilliant job cutting sandstone blocks, and was powerful enough to cut to full depth in seconds. It is not a powerful saw, so treat it with respect and it will do the work well.
The only negative is the pathetic plastic water lines. They are far too soft and it will either pinch closed or get torn apart on the work. Replace the cheap plastic lines with quality plastic line and you will be good to go.
It is not a professional saw, but it is very good for most jobs you need it for. One more thing, always use very heavy duty power cables, never the ordinary 10 amp extension lead and always use a good flow of water for cooling the blade.
