In-line on/off switch
From February 2019 forward, all units will have an on/off switch in the electrical cord which plugs into your outlet. We have in the past received comments about the lack of one from some customers who are (or were) electrical engineers. They claim that for starting/stopping an electrical device, plugging and unplugging the device from the wall is not an acceptable practice. While we have heard of no problem caused by previously shipped NuBall units, we added the switch to satisfy any future safety concerns.
