I loved my first UE Boom so much that I bought a 2nd one a paired it. The sound WAS amazing ... that is until the battery died in each of the units. The battery cannot be replaced nor does the company have any place to ship the spent battery to be recycled. Thus, this amazing speaker is nothing more than $200 worth of disposable heavy metals.
I am very disappointed as I used both speakers in a variety of ways. I travel internationally and often present in places that do not have good AV. I have a very nice Boxlight LED projector and paired with the UE Boom, I could do fabulous presentations to 100+ person audiences that were frequently amazed at what I could do out of a backpack. I also used the speaker(s) as my household sound system, in my car, blasting in the community garden, while riding my bike, almost everywhere ... as I write this review in the past tense.
The fact that the batteries are not replaceable nor recyclable and thus rendering the speaker unusable and disposable should be a crime. But then again, who in this screwed up world actually cares how or where these heavy metals are mined and what happens as they fill-up out landfills, erode and seep into our aquifers.
