Great little speaker!

Bought this for my son for his birthday. He loves it! He owned a previous version but it was stolen and he wanted to replace it with the same. He uses it at chess club at his university in a public space and it works well!

Purchased on Black Friday as a Christmas present, and it was a good deal. It is recommended by NYT wirecutter, so I feel it is a trusted and reliable speaker.
