JLab Crusher Review
J lab has been an excellent company for warranty support.  I keep two units, as I need music or noise when I am working.  13 hour charge is way over streching it.  But, I can live with about eight hours at a time,, if need I use the second unit as I charge the first.  My single disappoint is they do not furnish a outlet charger, a usb port is not always available to me.  I would and do reccommend these units to everyone. Same goes for the ear buds.
