This is a decent piece of kit well built fits well in your hand, it has plenty of power cuts well all round decent tool.
Can't say I can find anything on this tool that I particularly didn't like.

We run makita 18v saws usually but purchased a Stanley hedge cutter for my garden it is good so I thought I would try the saw but not so good for trade use. I will just use it at home

Great wee saw to use, super simple and light.
Could be slightly cheaper

It looks good and is easy to hold and handle.
The ergonomics are good on this saw.
For DIY it lasts a good while on a battery and the battery recharges quickly.
My biggest issue is the shoe. It's not straight and can't be adjusted. That means even following a straight edge it's not cutting straight. Which is the one thing you would buy a saw like this for.
It also doesn't lock at 90 degree vertical.
Finally a dust collector bag is useless on this saw - it needs suction to get any dust through the dust extractor.
