Take note, kiddies: mine *broke*. Luckily, it did not break completely mid-climb, but had cracked most of the way through under about 180 pounds of weight--enough that afterward it fell apart very easily. Although above it says "rated for 800 pounds," another seller says "not for climbing."

If you really want to be an urban ninja, get a real grappling hook from a mountain climbing supply store. 1 star

This is the best grappling hook ever i can now sneek into buildings quitley and attack with out warning. 5 stars

I bought this, not for scaling buildings, etc. but to grapple into trees and help guide them as I cut them down along my drive & fence line. I really wish I'd bought this thing years ago!!
It is made strong and well. It has also saved me hours of working on extension ladders attaching cables. The grappling hook also is handy guiding large, high limbs that need to be pruned away from property lines and other obsticles.
If you do much tree trimming/removal and can't afford professionals... well, plan your work carefully and plan on getting this grappling hook. It sure beats risking a fall of an extension ladder!

since i bought my grappling hook, i am now finally able to gain access into my ex wifes third story appartment... it was ble to break through the window and "grapple" the window all on the first throw! 5 stars

The grappling hook is sturdy enough to pull a large limb from the water. It's folding mechanism makes it more convient to store, but weakens it for really heavy pulling. 4 stars
