I like the saw, and once assembled and wired properly it is likely to be one of my frequently used tool. HOWEVER, READ CAREFULLY.It is a DC motor and comes with a AC/DC converter. Not one of those normal black plastic ones, it's a large DC Power supply. in a steel case (see the Amazon photos). This might be nice if you're a DIY geek, anyone else should look for a different model.The power supply is where the problems were located:1) The power supply was set to 220v. It's a subtle switch, be sure to change it if you are in a normal 110v residence.2) The power cord plug is a non-standard 50amp style wall plug *** UNGROWNDED *** (seriously???) This means purchasing a new end plug and understanding basic wiring.3) The power supply terminals are exposed to allow for adjustment. Not safe for a home environment, it belongs within an electrical enclosure. THERE IS NOT room in saw case for the power supply!4) The power supply voltage is adjustable with a small philips head pot (next to the terminals). Be sure to test is before connecting. Mine was 13.1V out of the box which is probably safe, and it didn't drop significantly under load, but I adjusted the voltage pot until it was 12.0Won’t turn on and now my return window is closed, this is my second one…What a waste of money :(Defective power supply unit.No power output from AC adaptor.
