a reliable top device

I do not know how many square meters, we have already worked with this sander. There are in any case amounts, and not once was, with the possible exception of the inevitable residual sanding dust, any problem in sight.

+ First-class, robust workmanship and quality
+ Best suction directly at grinding table - clear that the dust box accommodates only small amounts)
+ Top notch and the speed selection - is highly recommended !!!
+ All the features available and easy to use
+ Good to acting Weight
+ Sized ideal grinding surface (approximately 172cm²), which is also suitable for large areas
+ Easy to changing sanding sheet
+ Amazing "quiet"

Of course loops is an activity that requires simple experience and knowledge, you want to achieve the best surfaces, which then reflect, for example, even after a (expert) finish no errors). However, this sander is a good helper to you in this way.

There are certainly others, very good sander which is BO3711 any case one of them and I recommend it with best experiences you.
