The fact it’s a battery unit and portable/light.
It seems underpowered. This could be unfair as I haven’t owned other batter saws. But compared to a mains powered unit, it’s very likely to stall out.

This is my 5th battery powered Stanley product and it didn't disappoint. Although not as powerful as my corded saw, it is perfect for light cutting (ply etc) and with the battery, it is so good to grab it and it's ready to go. A breeze to use.
