Great replacement battery
Product comes with easy to follow directions. My Big Jambox is operating like new. This battery replacement is a great way to revive an expensive yet very good product (Jambox) that still competes well with other products in its price range.

Died after 14 months...
Died after 14 months of light use. So don't think you are repairing your jambox, I guess. You're buying a little while longer before the inevitable. Suggest you save the money and put towards a better bluetooth speaker...or a better battery, if such exists. Sad reflection of our world. At least dispose of the old Kratax battery responsibly, please.
