    I love this speaker! I wish it had the screw mount like the previous Mega Boom models, but otherwise it's perfect! I like the new location of the charging port, you no longer have to plug into the base and lay it on it's side. These seem to have no issues with charging, some of the earlier versions would stop charging after a while. The sound is very good, especially when you pair two or more together with the Mega Boom app.

    Works great, slightly louder and more robust than a regular Boom3 and battery life has been great over the month I've used it. Got on sale for 130 and it's definitely worth it. Not great in open spaces but does the job well in most environments.

    [Employee of bestbuy] It’s really good for a bluetooth speaker for spacious sound but not alot of bass. If you want heavy bass this is not for you. This is balanced pretty well on sound for a bluetooth speaker.
