I own the MGI Quad. I play on a hilly golf course with dirt/rocky cart paths. This type of terrain really is putting the caddie to the test. Unfortunately, the golf course seems to be winning. Many issues are beginning to happen .... Seat plastic tab that holds the seat frame to the bracket broke. Tires are starting to wear, and the male plug (12v) which is in the body of the caddie is broken. While I'm still using it, I lose power occasionally and must play with the plug to regain a connection. Going to try and use it until the end of the season before sending it back for warranty work.
