very good - fast - accurate - ware properly

Great thing - I as angler / camper I'm outside a lot and have a focus on a sound, so it does not bother me, because that device is not sooo compact as other bluetooth speaker. Solten it be with battery-3watt - does that sound not much - but latches gut.empfang through several rooms -from 15-20m crackles it then, because he is looking for (transmitter / receiver).
Although has no memory card slot, but I knew that beforehand.
