Review on Renewed Ultimate Ears Megaboom Charcoal Wireless Mobile Bluetooth Speaker - Waterproof and Shockproof by Brittany Jones

The design and sound are excellent. It took a few tries to get the "sticky" feature to work - here you can chain two (or more - apparently up to 100 or so) together. I use it in my bedroom for stereo effects. It would be nice to have a stretcher for the summer. The sound quality is excellent, even outdoors in a large garden. Out of respect for my neighbors, I hesitate to turn them up too loud. No star for that, but looking back, I should have gotten a basic two-speaker Bluetooth receiver for the bedroom. Turning on and recharging two speakers every once in a while isn't optimal. That being said, with the aforementioned excellent sound, they get the job done very well, even at low volumes.
