It's really cheap compared to other machines. I've rated it lower because the hoses and connectors provided did not fit each other, and the tap attachment is not hozelock or anything that would fit any UK taps. You'll need washers and mini pipe grips/cable ties/jubilee clips/siphon tube to stop leaks, hoses popping off etc.
But once you've done all that, it's really great to use. Motor is strong, gearing is slow and it runs pretty smooth for cheap kit. The polishing pads are easy to use, very durable and cheap to replace.
I've been using it to polish small areas (like 30cm x 30cm) of stone, concrete and kiln fired glass. I've been delighted with the finish, they are super glossy smooth and look great. I'd definitely recommend this tool.
