I also have this cart. I bought it from Costco in June, and I am so happy with it. I just hit the 225 mile mark on the odometer (45-50 rounds) and use it a Bethpage mostly which is moderately hilly. I bought this through Costco and got some of the add on with it (I don't use the seat/bench, but it comes with a cool seat/bench attachment). The battery life is great (over two rounds). The only mishap I had was during the Long Island Am in 100 degree heat when I was trying to drive it around the back of a green and really didn't know the course that well. Needless to say I drove it into the bunker on the 17th hole....
... kind of summed up the day I was having. Great piece of equipment, and well worth the investment. At $20 per cart ride, I already saved $900-1000 by taking this instead of a cart in one season.
