I gambled and bought the HF sale item, and threw a couple of their belt assortments in the cart . I had previously bought some non woven belt and coarse belt assortments off eBay from econoway abrasives and proabrasives. Will see how they perform some time. (Worst case hoping the parts are interchangeable with a B&D model I bought with only the point arm.)
Just got around to opening the box from HF. Nothing spectacular, nothing awful either. It does run, and came with two spare red belts, and one installed. Think they are all 36 grit. Bought a couple of spares too.
I love that they repurposed an angle grinder to make it work, but didn't bother to call out the spindle lock button in the manual (don't press while running). The side holes for mounting an extra handle might come in handy, suspect I can re use any foreign made tool's handle as a donor.
I have not had much time to play with things, as noted, so no idea how well it will in a home hackers shop.
Parts will not be interchangeable with my B&D unit.
