This is a really nice piece of kit. I bought it for moving boulders in my yard, and I'm really happy. The blocks are very strong and easy to adjust due to their \"snatch block\" style construction. The rope has a durable cover that doesn't snag on the ground or tree branches. My only criticism, and it is only a small one, is about how the rope is packaged. It is in a really tight bundle that falls apart as soon as you release the straps, leaving you with a twisted up mess. If that happens to you, get a helper and take the extra 5 minutes to remove *all* of the twist from the rope before you thread it through the pulleys. If you don't, the lines won't run smoothly through the pulleys and you'll lose a lot of pulling force. Finally, do yourself a favor and get a 3-5 locking carabiners (usually rated at 25kn or more) along with this purchase -- they make it really easy to rig up your anchor points, slings, etc.
