Very good sounds, very good bass, very good battery life and ver portable.

This speaker takes up very little space and sounds great! I love that it is easy to use, durable and expandable. I only have one at the moment but use it very often and plan to get a few more.

For the money, this a fantastic speaker that is now water proof. Great sound and volume & very good battery life between charges. A solid choice with no regrets!

Happily pleased by full nuanced sound, and the charge lasts longer then other such devices. Also like the cheery colors and shape

So, I've had this speaker for a while now and it is above par in sound and convenience. I’ve used it for indoor and outdoor activities. Size of this specific speaker is perfect when I go on bike rides and put it in my bottle holder and control everything from the app on my phone that is positioned on my handle bars. The double up feature is cool when two of these speakers are involved. Battery life is decent compared to some other products, but it really depends on my total use. When I’m really active I would say I charge every two to three days. Overall worth the buy especially when I bought on sale.
