...ordered proper handle for my model of Samsung microwave, which was black and plastic rather than silver and metal - that's okay because black still goes with the silver & black oven - at $20 instead of the ridiculously high cost for an OEM, removed the old screws and the bits of PLASTIC left around the screws, and screwed the new handle onto the door using those old screws...total time including removing and replacing the door and plastic bezel inside the door: 10 minutes!
...fairly easy replacement.
...2 dots for how challenging it was only because the effort it took in aligning and reinstalling the door with and into the holes.
