The maker claims it's "Longitudinally compressionless yet laterally ultra-flexible and also totally corrosion free!" That, I don't debate. But the price is something to consider: €220 for a complete set. That's about $US 300. That buys a lot of replacement traditional cable housing.
Maybe most interesting of all is that the business is run out of the Canary Islands.
