This duck is in my bathroom for many years. Is often times at Penny on offer, the price here is too high. I'm very satisfied with the duck, for the price, the sound is great and the service life high. Only the transmitter can be adjusted poorly, so it's best to adjust 1x favorite stations and stick to it. If the volume begins to fluctuate, new batteries are due. Batteries should last for about 2-3 months.
