I love my Cart Tek. I have already used it about 20 times from 9-18 multiple times. I do have a couple complaints but nothing major. First, I dropped the remote once and it stopped working (my fault for dropping it). I did not have a screwdriver with me to put the batteries back into the channel but once I got home I pulled the screw out reset the batteries and everything was fine. I keep a little screw driver in my bag now. Second, My Umbrella holder snapped at the base after the first use. My course is pretty bumpy so maybe that was the issue but it shouldn't snap. That is why I did 4-5 stars.
