I recently purchased the MGI Zip Navigator AT - All Terrain. I have used it for 27 holes and it as tipped over 5 times. I like playing early in the morning so there is dew on the grass and the coarse I play is hilly. Each time the cart as tipped over the wheels just spins going up hill with no traction and eventually tipping over before I can rescue it. I thought the AT was a all Terrain electric golf caddy but I was mistaken. I'm extremely disappointed with it and wish I could return it. The return policy requires I return it by 30 days from the purchase date which has came and passed.
