My experience with the product is limited to about 3 weeks of fairly intense use. I ordered this as a vital component of my ninja training, and it arrived rapidly and in discreet packaging. So far it has proven to be fairly sturdy and reliable. Build quality is good and is has held up well under regular use, though I would not place more than 200 lbs of load on the provided rope. I have used this to scale all sorts of urban environments in security and stealth, and the collapsible nature of the product allows it to fit comfortably on my utility belt. Once my training is complete, I fully expect this will be an invaluable piece of equipment in my one man crusade against crime. Evildoers beware!

This product was everything it claimed to be. It folds flat.

Being a desert hiker, I had hoped to climb sand/rock hills by throwing the grappling hook and pulling myself up. The hook usually skates over the surface and does not dig in until it hits a shrub or cactus. It could be useful in a group hike if one person gets to the top to hook it by hand. My expectation was wrong but I carry it in my car for emergencies.

We orderd this product to help remove lake weeds. It works great for that, It is well made and Im sure ninjas will be impressed with it.

The grappling hook is a pretty decent product for the price. I have no clue if would be effective in scaling a wall or whatever it is that Ninja's do, but it does work for latching onto debris in my pond and some pond dredging. I have noticed that other reviewers have found this to be a useful tool in yard work. I suspect that this product may be marketed incorrectly. A real grappling hook such as used by SWAT, etc. can cost over a hundred dollars and there does not seem to be anything in between a professional grappling hook and the Ninja grappling hook. As a niche product, it works pretty well.

This is OK for use in tree cutting although I did bend one of the tines on it. But I wouldn't bet my life on it for rappeling. But for the price it is OK.
