Received one for Xmas last year. Loved it. Worked great… For five months. Then it just stopped charging (it doesn’t work plugged in either so no using by the toilet to avoid in-shower electrocution). Don’t bother. Buy a jam With a BB&B coupon and blast the volume enough to hear in the shower. That’s what I went back to.
Found it on Amazon for $5 less (https://www.amazon.com/Wireless-Bluetooth-Waterproof-Speaker-Dedicated/dp/B00O2L4KXG). When I went to checkout, it looks like shipping is also free. Killin’ me, Woot!
[MOD EDIT] Different brand and not in stock until 12/21.
