“This review from Treetools provides a technical comparison between the Kong Duck and the Wild Country Ropeman. It highlights that the Kong Duck was designed with the shortcomings of the original Ropeman in mind. A significant advantage of the Duck is its cam design, which features a non-aggressive tooth pattern, reducing the risk of severing the rope sheath under load, a known issue with the original Ropeman. The Duck is certified as a 'rope clamp' and is designed to slip between 2.5 kN and 6 kN of static force, unlike the Ropeman I which severed the rope sheath at 4 kN.”

“A user on the Mountain Project forum shares a mixed experience with the Kong Duck. The user was initially drawn to its small size, light weight, and ridged design for use as a personal anchor system (PAS). However, they express concerns about the build quality, describing it as feeling "a bit cheaply made." The main issue reported is the side plate bending after repeated light use, raising questions about its structural integrity and long-term reliability, especially for real-world applications. The device was also noted as being picky about the shape of the carabiner used with it.”

“This blog post compares the Kong Duck to the Petzl Mini Traxion for ski mountaineering. The primary advantages of the Kong Duck are its significantly lower weight (70g) and smaller size, making it easy to carry. The reviewer also notes that its less aggressive teeth cause less wear on the rope and that it can be used on flat slings. However, the Mini Traxion is considered the better overall device if weight is not a concern, as the Duck creates more friction in a hauling system due to the lack of a pulley and its design causing the rope to rub against the teeth.”

“This video compares the Wild Country Ropeman 1 and the Kong Duck for saddle hunting. The reviewer notes that the main reason for choosing the Kong Duck was its compatibility with smaller diameter ropes, down to 8mm, whereas the Ropeman 1 is limited to 10mm and larger. A key feature highlighted is that the Kong Duck doesn't require a carabiner to be locked in on the rope, which the reviewer prefers for tether use. While both are recommended, the Ropeman 1 is suggested for a lineman's belt due to better adjustability with an oval carabiner, and the Kong Duck is preferred for the tether.”

“The Kong Duck is praised for being significantly lighter and smaller than typical handled ascenders, making it comparable in size and weight to other rope grabs like the Wild Country Ropeman and Petzl Basic. Its versatility is a key advantage, as it can function as an ascender, a progress capture device in hauling systems, and a length adjuster for safety lines on both ropes and flat webbing. However, the review points out limitations, primarily the risk of overloading the device, as Kong specifies not to shock load it or haul more than 400lbs. Unlike devices with teeth, the Duck uses a spring-loaded cam, which is a positive for not damaging the rope sheath but may have a lower maximum load compared to some competitors.”
