Great cart, great design, built like a tank, and a superior way to play golf on a hilly course. It's proven to be stable, as well, and I haven't tipped it once.
I think Alphard has done a fantastic job on the design and build of the CyberCart.
The biggest drawback, for me, is that it is a bit clumsy to expand and collapse. Once you get it set up, though, it's easy to operate. That's why I gave it 4/5 stars, but it really deserves 4.5/5.
