The power supply is important for long exercises. The batteries decrease in power and thus produce discordant sounds.
Device and service o.K

Where there were problems, with the parcel delivery driver at the delivery.
Why not another?
So I had to drive 5 km, because there is no service station on site of your parcel delivery, although many people are at home here...

With kind regards
