Bests & Worsts Reviews from Amazon

I want to say first that this speaker rocks! It is loud with great quality sound. It only lasts about 6 hours with the volume all the way up. It also does not connect to the Flip 4...yet. I called JBL customer service and found out they are planning to update the software August 2017 to allow the xtreme to connect to the Flip 4. But BEWARE of Amazon units. The unit I bought from Amazon said "Europe" on the bottom of the box and there was no serial number on the speaker itself. However, I did not realize this until I bought a second unit from a local store. I like my xtreme so much that I wanted a second and there was a sale locally. When I got my second unit I saw that the UPC on the box says "Americas" and the speaker itself has a serial number on it. I added to pictures to show the box and serial number. In both pictures, the Amazon unit is on top. Update 6 Jul 17: The new one I bought that is an American edition has lasted much longer on the battery. I have not tested it straight, but I would say I have over 6 hours on it and still have over half battery. That is at about half to 3/4 volume. In the upcoming weeks I will be at the beach and I intend to do a full volume test to see how much life I can get.
