I initially was happy with my purchase, but after a few months of use the battery wouldn't hold a full charge and would lose the first 2 bars in 10 min of use

It also can be used as a big external battery for your phone!Highly recommended!

and it has a pretty good battery life.

This battery is a huge disappointment it stopped working out of nowhere only after using it for 2 months

Probably a battery issue

Has really great sound, and good battery life.

Stellar battery life (though that is diminishing somewhat with age), room filling sound, and truly waterproof (submerged several times over the years and wet even more).

has awesome sound quality and good battery life, love the product, would purchase again

Great sound for a portable speaker, feels very durable, good battery life so far

Definitely waterproof, great battery life, and good sound quality

Amazing speaker, great sound, long battery life

More than long enough battery life

When you turn one off it turns the other off for you, it would be great if they would have one turn the other on and add NFC functionality for binding the two speaker together instead of having them look for each other sound quality is fantastic battery life is great

Good battery life, great sound quality, and the option to charge your phone make this a 5 star product!

Will drain battery very quickly :)Great speaker and was definitely worth the purchase when it was on sale.

Great battery life.

BUT the battery sucks

The battery has been amazing, it holds a charge for days of intermittent play, and still has a charge if I don't use it for a few weeks.- Form factor

and wow...what a great battery life.

Great sound, good battery life (i've gotten 8+ hours out of it).

Great battery life.

it's great sound and battery that lasts forever

Super loud, water proof, great battery life.

It won't break easily, awesome battery life and great sound

That being said, don't throw it in the pool and expect it to work just the same as it had.
