I received it as a birthday gift, and had to take it out and use it two days after receiving it. It was 35 degrees out when I teed off and everything worked perfectly! It warmed up to 60 degrees a few hours later and I noticed no change in performance. It climbed every hill with ease, and the parking break kept the cart in place on most of the sever slopes, but there was one where I had to turn the cart to keep it in place. The online videos and reviews were helpful, especially with regards to the four pre-programmed speeds. Just a quality product! I am so grateful to own one of these because I prefer to walk when I play, but pushing a cart in my 70's is not getting any easier, and this is just perfect for me!
