The mat took three weeks to arrive. It was marked as shipped the day after I ordered it. Customer service told me three separate times that it had shipped, and I would have it in three days. I can't figure out what the problem was. Clearly, it hadn't shipped. You can't speak directly to a customer service representative when you call. You have to leave a message, but I did get a call back on each occasion that I called. The mat wasn't exactly what I thought it would be. It is pretty similar to a mat that you would buy to put a piece of heavy workout equipment on. It works just fine, but nothing too spectacular.
All and all, I think that these are high quality ropes and worth what I paid. Crossropes has a 30 day challenge that gives you 30 days of rope workouts in a pdf, and they have you-tube videos to help you learn different jumps. They even have an fb group to help keep you motivated. I wish that I would have waited and gotten the infinity ropes. The handles look like they offer easier exchanges between ropes. The infinity wasn't available when I ordered and I won't be investing in another set anytime soon.
If you are willing to pay $70 for jump ropes, I'd say go ahead. A one pound rope really isn't all that cheap. You could definitely find a quarter pound rope and a one pound rope for less than $70, but I would guess you wouldn't get as good a product. I'm not sure most people need the highest quality ropes in the world. How many people jump exclusively for cardo? If you do intend to jump every day, you might want to spend the money.
