This portable radio delivers good sound and reception quality is good too. I put rechargeable AA batteries, the same as in my phones, suddenly if the radio falters I change with a phone and presto, even need charger! Autonomy can go up to a week when you listen every day. Once installed its stabilization is quite good, and its dimensions make it take you anywhere. The only thing that is annoying is the price, it fell by a little over 5 between my order and two days later when I received it. More than 30 expect. One star less because of the price.
