I travel a lot giving talks with powerpoint slides and videos, and have learned not to rely on local staff to have the A/V setup figured out. This little speaker has become indispensable to me, and I take it on every trip. It's light enough that I don't even notice it in my briefcase, but it's powerful enough that it filled a hotel conference room (30'x30') with crystal clear audio via bluetooth from my laptop.
I also can't say enough about the customer service provided by Pac2Go. I recently ordered a second speaker when the first one stopped working unexpectedly. I sent a message to the company, and got a phone call back *within 3 minutes* saying that they would be happy to replace it. It was in the mail before the end of the day.
