Functionality yes, good quality

Ordered as a substitute for a delta sander device. One might assume that everything fits in the BOSCH professional. But unfortunately, the unit developed the volume of an aircraft turbine and abrasive pads fall virtually on its own again. So both during grinding and during idling. Will return the equipment, order replacement.
Functionality is ok. Especially with the battery a great machine, if the above problems were not.
Will revise the review, if the replacement product has been tested.
Let's see if that was only a C-quality ....
Update:
The replacement device is there, and lo and behold, it is not as loud as the first (Friday birth probably :)).! I would say excellent, only problem remains the sanding pad, the pads fall still on alone, so in a Relationship inferior.
In the meantime I had a Einhell MT-RG (OAU) also with battery, hoping the battery would be compatible, but they are not, power and volume were ok. Big plus the Einhell, the sanding pad keeps the pads of something solid, great! Big minus the battery performance at 1.3Ah is not enough long. Batteries with more Kappazität there is simply not and spare batteries are very expensive.
In this sense, I Bosch GOP recommend, especially if you are already equipped with the corresponding cordless tools. Another 2 Ah - Battery to and completed.
