FYI
Returned the Mac Disaster circular saw to B&Q and got a full refund, ordered the Makita. £45 refund, £80 for the Makita so I ended up spending an extra £35. What a difference!
I wanted a 165mm saw to save space on the van & to keep the weight down in use. I don't cut anything thicker than 50nn so the 54mm depth of cut is fine,
First used in anger today, what a superb machine, only 950w but like the other Makita stuff I have it punches well above its weight.
Absolute joy to use, well balanced, rip fence & bevel adjustments very positive. Nice feature is a 'V' shaped notch for 0 & 90 degree cuts, but this has a flat at the base the same width as the blade kerf, so you can cut either side of a line.
Riving knife can be removed in seconds for plunge cuts.
I'd highly recommend it.
