Best portable speaker

I work construction and the last one I had it took a lot of abuse, I mean a lot more than it was intended for. It’s rare to own an electronic device that you can knock off a ladder countless times from 10 to an 8 down to a 6 and it never cracked the casing or damaged the speakers. Also One time I was building a deck 8 ft off ground and it came a storm and like always I let it set in the rain because it’s water proof ( I don’t think you can swim with it ) well direct rain or heavy moisture doesn’t bother it , but I was getting up my power tools and knocked it over with one of the cords getting tools up and it rolled off the print table and rolled right off the deck in to some flooding from the rain and floated all the way down the side off the house and end up in a pool rain water . At the moment I didn’t realize it rolled off the deck and floated away and after five six mins looking for it I found it on the side of house laying in water I was worried for first time it had of met its match and that was it . I pushed the power button and it lit right on up and worked perfectly. Several months later someone sole it . But it’s been a year being without it and I’ve missed it every since .
I made a lick of money a small lick but today I bit the bullet and bought me a brand new spanking new one ,

Finally a good app that actually works well

I have been trying out other similar apps as this one well my efforts for now have been ended be no matter what you try to seek because every thing that you may be looking for all right here for a good price and very good sound and clarity I believe if you do try too that you too will be satisfied as well. They offer the best price out there for time wise and with what they give you you will be staying the same thing a me too If this kind of app is what you have been wishing to find. Thanks for your service but hey who ever you are that ingrates back to these reviews do you think that maybe if times may start to get bumpy for myself and I may have to skip a subscription for what ever reason do you guy’s offer any kick backs in an extra month or so that would really put you all up on top then but really thats cool if you all could slide an opinion over to a brother. Thanks.

Good purchase

Good purchase but was hoping for a couple extra features but I’m very confident future updates will be worth the money for the annual subscription- annual subscription buyer.
