Is that the same as the DAS21E? If so I think they are unbeatable performance for the money... http://www.cleanyourcar.co.uk/polishing-machines/vertool-das-21e-dual-action-polisher-v2-/prod_1391.html
I have one, MUCH better than the DAS6 I borrowed
to try, the bigger 21mm orbit really cuts a lot better than the 6 mm the DAS6 means the job takes a fraction of the time.
Do you find the 21mm orbit restricts you in any way in the tighter areas? It's certainly a big plus on the larger panels but I'm wondering about the tricky little areas where I use a 3" pad.
