I use this unit for 4 years. What's great is being able to walk without looking back if the jack does not cling.
rendering sound is impeccable, I'm going relatively far from the source and it is always such good sound.
Consumption level I can not say too much since I use rechargeable batteries but it did not seem to pump énormemment.
While away the antennae and prominent position if possible after it rolls
I recommend it if you walk a lot of live or no interest.
