Fine, but the description is a little "rumbling"

The sander itself is quite efficient. The small dimensions allow the use of average areas or places not necessarily very accessible (inside a closet). The weight is reasonable. the grip can work well.
I had a sander of the same brand, the performance here is largely superior.
The removable drive protection sanding allows to approach closer to the edges, but the diameter keep you away from the angles (bring a small triangular head sander for finishing anyway).
It is rather at the accessories that it gets stuck ... not that they are bad (far from it), but the description seemed to promise a little more.
On "10" accessories do count as 3 for sanding + The Collector. Forget multiple drives and media seen in the video, the sander is delivered with support for disks (and a few disks), a plastic bristle brush and an accessory for "scratch" the tapestries to facilitate their elimination.
The accessory that looks like a vacuum cleaner is only a dust collector motor ... no ... the advantage is that the motor is not therefore clog, but the effectiveness is not problems. uU least the filter is easy to clean (thanks plaster). Instead, try to connect a vacuum cleaner construction (including a model that automatically starts the switching on your device).
The remains optional fee ... but promising; metal brushes disc for concrete and stone ... my old staircase begging me to equip myself ... I think I'll listen.
