Best remote trolley I've ever owned. Performs as advertised. I have used my MGI Zip Navigator AT for 6 rounds on my very hilly home course. It goes up and down hills with ease without falling over even once. The four wheels, with independent front wheels, create a very stable platform. I have owned other power trolleys before and this is by far a much superior solution. The integrated gyro is a godsend. It keeps the trolley tracking on a straight line when it's being navigated by the remote. This is an important feature that should not be overlooked. This greatly reduces the need to keep fiddling with the remote to course-correct the trolley as it rolls down the fairway. Your thumb and wrist will thank you. The remote buttons are large enough that it's easy to operate without having to look down at the remote. The buttons are large enough that you can easily feel each individual button. My previous trolley had a small remote with small buttons. It was difficult to operate without looking at the remote. You will also appreciate this on cold days when you want to keep your hands in your pocket while operating the remote.
