Audience aR6-TSS Power Conidtionor

I’m using an Audience aR6-TSS Power Conditioner since last year Summer and I just love it. Everytime after I use it, I will switch it off, but Audience’s dealer told me unless I’m not at home for a long period. Otherwise, I better to turn it on continually everyday without switch it off.  Otherwise, the switch may worn out later if I turn it it on and off everyday.   I don’t feel safe if I switch it on continually, especially when I left home to work. So what is the correct answer?
