not sure since i have no use for it. i think if you have a vac with bluetooth it will turn it on and off ? i just plug the sander into my vac and it already does that so it's just another thing nobody needs. ask the duck he loves that shit. he's mentioned all the bluetooth tools he has.
working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.
