I have stayed away from their products because I feel like all the pseudo scientific mumbo jumbo they put out is used to obfuscate their cables actual properties and construction. For all I know their products are simply re jacketed Belden or similar where they then charge a ridiculous mark up. Fine with me they gotta eat too but I will pass. To be fair they are far from the only ones doing this and may not even be the biggest offenders.
Ars Technica did a teardown of one of their ethernet cables that cost $350.

Looks to me like it's about $30 worth of actual materials and kind of cheaply put together at that. It makes all of their products pseudo scientific mumbo jumboish claims suspect to me.
Again I don't dislike them, they just in my opinion make a product that they have not proven to me to be any better than something costing a fraction of the cost. If they look nicer and people like that far be it for me to tell them how to spend their money. But I will not be a consumer of their wares nor a believer in their marketing materials.
