I don't know about the metabo. It takes a little bit more time to polish a car because you have to keep looking at the speed dial to change rpm. It does have a short soft start and does have torque.
Here's some answer I got from pro detail when I ask which rotary did they like that they have use
From TH0001:
I used to use the Hitachi but started using the Makita when I had starting having problems with the Hitachi. I like the extra weight and better durability, as well as the soft start, of the Makita. Its the right size, weight, and smoothness.
From Dave KG:
Hello there,
The metabo was not my rotary, I was however trying it out tosee what it was like. I personally own a Makita 9227CB, and after trying the Metabo, I will be sticking with the Makita. The metabo, while being a lighter tool and this being an advantage on side panels for example, I find ergonomically poor. The Makita, despite being heavier, I find easier to handle and more geared to spending a long time with the tool. Additionally, the speed control on the Metabo is crazily placed, similar to a PC, which makes it a pest to adjust speed when in operation. The Makita has its speed control right next to your thumb by contrast.
Cheers,
Dave
