I used 3m and Duragold. None of them could be found so I ordered this one. Needed more than 3000 but thought 5000 and 7000 would be cool for better shine. The 3000 model was inferior to the 3m model, leaving scratches and curls. The 3m was slightly better but oddly the Duragold brand was the best. I wouldn't recommend it for wet sanding at all.
