very good reconditioned product, one drawback is the battery life: 3 hours isn't much when you need to last a whole evening, and maybe I didn't look carefully but I didn't see any warranty.

Battery of the device defective the salesman did not check anything! Didn't clean the speaker to make it look professional. They asked me to send it back. I want to keep it but I have no certainty that they will repair it even though it is repairable.
