worst customer service ever! Dont buy any products here. I bought a dual arm set for my Gates, and the motherboard did not work. I emailed, I called, I left messages, I could not get anyone on the phone and when I did they said send a picture I said well I'm sending you a picture of a motherboard----- that doesn't work that doesn't make any sense So I have so I had to go buy a whole new set after my contractor had installed the arms there was no there was no customer support I will I would have glad have gladly paid more for any other brand than have to spend 3 days not getting out of my driveway because I couldn't get anybody to call me back I eventually had to solder off the arms of my gate because they would not send me a new motherboard
