This is a great solution for anyone who needs a totally wireless system. Just bring the speaker and you've got amplification anywhere without power or wires.
The Bluetooth works great. Sound production is very good. Battery does it's job. Nice carrying handle.
The only unanswered question is to determine the charge remaining on the battery. Not yet sure what happens when the battery drains down near to exhausted. Didn't see anything in the manual and the folks from Samson never replied to my query via their website.
