I purchased this rope to use for learning double-unders for CrossFit workouts. I was not having much luck with the very thin cable speed ropes that we have at our box, so I was thinking about buying an RX jump rope that are very popular. Luckily for me I am 6' tall, so a 9' rope works out perfectly. I got this rope, spent about 30 minutes getting used to it and started hitting double-unders for the first time with ease. The cable is much heavier than the speed ropes I had been trying with, and that really helped get some feedback to my wrists. Anyway, I suppose I will probably buy an RX rope at some point. Comparatively these handles are a little bit lighter, and the bearing mechanism is half made of plastic, instead of all metal. I plan to wait until I am good enough to get a thinner cable for speed. Right now this rope is perfect for me to learn on, and I was out a lot less money. I would definitely recommend this to other people... but only if a 9' rope is the right size for them, as these are not adjustable. If you aren't within an inch or two either way from 6', you should probably get something else.
Love this rope! My ONLY complaint, is that being new to the jump-rope world, I didn't know that jump ropes are NOT one size fits all. Make sure you know ahead of time what size length rope you need--this one IS NOT adjustable. (In my case, I was lucky enough to have a handy-man husband who was able to cut/reassemble the rope to the length I needed--I am 5'5.5" and had to cut about a foot off the length).
