Pros:- Quality and durability: the speaker is built well, seems quite rugged and has an IPX5 rating.- Ease-of-use: the Bluetooth button on the speaker makes pairing a breeze, and the additional buttons on the speaker, which include a play and volume increase and decrease button make controlling tracks easier, though not to perfection; I would have liked to see a next/previous track button.- Performance: the Bluetooth pairs well with my phone and does not stutter, and its range is exceptional.- Sound quality: the sound reproduction is great, though the bass seems to suffer when you surpass 60-70% volume.- Battery life: the speaker lasts multiple days without the need to charge it.- Color availability: the speaker is offered in black, blue and red.- Warranty: like all Anker products, this speaker is backed by an 18-month warranty, and in my experience, Anker has always stood by their products with amazing support

Has great range and volume.

Loud, clear, long range and battery life is outstanding

The range and connection is reliable enough for me to leave my phone outside of the wet environment without worrying about sound distortion

The range as well is quite decent, as I can walk quite a distance from my phone before the Bluetooth disconnects

Loud, clear, long range and battery life is outstanding
