DO NOT USE THIS FOR ANY CLIMBING PURPOSES
Seriously, if you want to climb cliffs take up climbing as a hobby, learn the ropes, build your physical abilities and get purpose built climbing gear.
I can totally see someone sitting at the bottom of a cliff and throwing this thing at cracks until it sticks, then falling to their deaths. Furthermore, climbing gear is designed for..... well, climbing. The engineers have foreseen nearly every weird circumstance that can occur and have planned for it. Then they use extremely low tolerance (high precision) manufacturing techniques that ensure no single piece in a batch of 100,000 has a single defect and will stand up to nearly 10 times the amount of force they'll ever realistically be exposed to. After that an entire staff of people are payed to ensure that manufacturing process went perfectly and an army of lawyers has outlined how absurdly safe and failproof all this stuff will be so the insurance company can safely insure them.
The same goes for tree climbing gear.
This thing though? Likely being made in china by sweatshop workers who could care less about the corners they cut and actually have a tolerance for shitty singles in the batch. Not to bash the product for other uses, that isn't the point of this rant. The point is your safety. In one of the videos they pull a car from a stop and he mentions that the hook bent. Chances are there was never more than 4 or 500lbs of force on this thing before it began to fail (the max force exerted can't be more than the cars torque plus or minus a little, which is most likely around HALF of that figure) A solid climbing fall can do upwards of 2000lbs of force........ Ever jumped on a scale and watched it rocket past your weight? 150lbs falling exerts more than 150lbs of force is why.
Anyways, go ahead and buy it if you want to do some neat grappling hook shit. Only use it for tree climbing and rock climbing if you want to die.
