I have the D575 dozer and the HD785-7 mine truck. Both operate and are ok to push/haul lightweight stuff around but certainly not intended to be hobby-grade models. Note they are infrared not radio controlled. Line-of-sight is required for operation. I got them because I work for a Komatsu dealer as a technical trainer and use them for promotional and fun purposes during classes. Mostly they are displayed in my office. If you intend to use them as a working model for hobby purposes, I'd say save your money. If they are for display and occasional fun use, they work great.
