I have contacted ordered 60 because I've only heard good things about it, and it knew from earlier times. The switch my coffee could no longer turn on. Once roughly sprayed with contact 60, and it works perfectly again. A second attempt with my old Opel car key remote control (it worked only occasionally), and this problem was solved. Contact 60 has made for me umpteen times already paid for, and can be recommended for contact problems only highly.
