I'm wondering to all the seasoned Don users as I've only owned mine for 5 weeks if there's a need for extra parts to have on hand- switches, buttons?? I diligently clean my Don every 1 1/2 weeks and try to keep it in tip top shape. Still love my Don and it does perform extremely well beyond my original expectations. DC Cartos are a HUGE + and next will be looking into buying a tank = MORE research 
Thanks for any feedback, Vapoor.
