I’m really late on this discussion but I just tripped across it and Felt like adding my 2 cents…
I have the PowerSpec 3D Pro and not one single complaint about the machine. A little nervous at first but that was quickly
gone. This thing has been outstanding and given nothing but excellent results. the only limitation really was ReplicatorG but
the pricetag left me plenty of room to buy Simplify3d and a firmware flash. For a clone it’s been impressive. Stay away from cheap filament and enjoy a good experience
