This is a very nice speaker at a great price. Only "issue" we had was that it would cut out when phone was inside and speaker was outside. It was never a major problem though. It came back in on its own. We have used this a lot during a garage remodel.....battery lasts all day and gets plenty loud enough.
This speaker is a little powerhouse. The sound is crisp and clear and can go pretty loud. I had a little trouble getting it to work with my echo dot but once I managed to get them to connect it was smooth sailing. This is a great little speaker for the price.
