I own, many, many speed ropes. About 2 years ago I went on a kick where I was convinced the issue I was having with double unders was the rope, and not me. It was me. Anyway, I have tried many ropes, with many different methods used to make them move fast.
About the rope:
The Bear Komplex Hummer Speed Rope has an aluminum handle with an interesting pass through design, that essentially uses a one way valve to feed the rope out or quickly change the length. A very cool idea. The handles have a nice knurl and a good weight to them. They feel far more substantial in the hand than say an RPM or Elite SRS speed rope. The bearings have a good spin to them and that's pretty much all there is to talk about, its a jump rope.
What I like:
Personally I love the weight and girth of the handles. I mean I know it's not for everyone, but I like it a little on the thick side. For my hands it just feels better. Combined with the weight it gives me a better feel for how the rope is moving and lets me time my jumps better. (I am bad at jump rope, keep that in mind)
The pass through handles are nice for those of us who constantly believe our only issue is that we don't quite have it dialed in yet. You essentially only have the length of the handle to play with so I don't think I could hand my rope to my wife and she's be able to adjust it to her height, but honestly she gave me a Hummer so I should probably give her a Hummer as well, though she might take it the wrong way depending on what she thought I was implying, however they do have a blue one, you know what give your wife a hummer, she deserves it.
What I don't like:
This isn't so much of a don't like as a concern. The way the rope feeds out of the handles is super neat. Unfortunately, I've seen a few reviews complaining about that mechanism failing, and it's just one of those cool, but potentially overcomplicated mechanical solutions that could become a point of failure. Mine has not failed, it's been fantastic.
The other thing about the handles is with the straight out the end design, you develop a bend in the rope very quickly, which does make it a bit more prone to tangling and might eventually cause in issue with the cable itself. Again mine is holding up great.
Conclusion:
The rope is $30 bucks, comes in black and green (also blue I guess), and feels great. In this price range I think its as good as any of it's competitors I've used so far, and it's my go to, and rest assured I have many more expensive ropes on my wall. So I think it's worth the money.
