I bought the tip top AI Navigator. Works fine on flat grass and pavement, but the photos make it look far wider and stable than it actually is. Mine has tipped over 4X so far, the latest being when the buggy approached a small dirt-to-concrete lip of no more than 1.25 inches. The anti-tip wheelie wheel doesn't really assist in many situations, it simply isn't long enough. Another treat? I have learned that when my buggy tips over, some sensor must tell the wheels to go full throttle. I need to film it when it happens and send it to MGI. It makes a bad situation far worse. One tip-over was near a sand trap, and not on really uneven terrain. I play at a Denver City Course so no mountain terrain or anything like that. Yep, started to tip, and went into full launch mode. My stuff ended up packed with sand, including my phone and phone holder, which now hardly will open or close until I can get all of the sand cleared out. Is the thing cool and does it so what it says? Yes, on very flat terrain. A couple of fellow club members have the same issue. They like their buggy, except for, like me, tipping over 4X in 36 holes. For close to $2K, I wish I would have looked closer at the specs as far as width, etc.
