Summary: Poor volume. I bought this for outdoor use by the pool. When connected by Bluetooth, volume loss is close to 25% (by my less than trained ear) versus cable connection. This defeats the purpose (too many iPhone upgrades due to water damage). Look elsewhwere for another unit.
Summary: Pros: I liked the rubberized look and feel of this speaker. The rubber texture and metal grilles were nice and make it feel sturdy. I was initially happy as this unit performed well for me at work. It was easy to pair. Sound was adequate. Fits in standard bottle cages.
