Excellent!
Fast delivery, flawless material - price-performance is reasonable. Beautiful color and pattern. I use it as a main halyard on our pogo.

Good
A nice piece of rope. We had to replace a reef line on our catamaran. This was close to the one that came with our boat.
Shipping was fast. Only took 3 12 weeks to ship to portugal.
