Thumb Score: +2
I personally have been using Braven Pro for 14 months, and it has been the best outdoor/rugged Bluetooth speaker I have tested. The speaker itself is now retailed for 89 dollars at BestBuy, without any accessories. This 40 dollar bundle comes either with a solar panel module or a powrbank module you can attach to the speaker to give it some extra boost.
For the solar panel bundle:
