My job rocker was defective, and customer service was like going to the dentist.

My husband uses the Job Rocker Plus on his job sites and he just loves it.

This ION Audio Job Rocker Plus is just plain awesome

As far as performance, the Job Rocker sounds great but you must keep the volume of your mobile device well below max.

Completely satisfied with this item...great sound and charge lasts very long time, even when 120vac outlets are in use...built very well...have owned for 1-1/2 years now and still works great...have used at work, parties, and family functions, and has performed well every time...bluetooth range is awesome...would highly recommend Job Rocker to every one !
