I have a couple devices that will not charge with a USBc to USBc unless the cable meets some sort of minimum spec. Most inexpensive cables I've purchased don't work. This cable works. The connections feel good and are reliable while moving the cable around. I would consider the flexibility average. As for the printed claim I have no way of checking that. I purchased this one because of reviews and company reputation.

There aren't much thunderbolt 5 devices out yet, but this thick cable is future proof and ready to handle upcoming devices. This cable is not as cheap as some of the other cables you can find online, but, it is from a local American company with a strong reputation. Many of the other "American" branded companies in the accessories market are like shell companies of a dozen American employees or less that outsource everything else overseas. OWC employs hundreds of US workers.You get what you pay for, and in this case I think it's a high quality cable from an American company.I noticed that even in apples to apples comparisons (such as fast charging a device only capable of 40 watts) this cable performs marginally better than other cables. Like 40.7 vs 41.7, it's not much, but it's interesting to note. I guess maybe it's because of the quality of the cable and the requirements of the thunderbolt 5 standard let it squeeze just a little bit more into devices?Don't expect significant gains unless you're using an actual thunderbolt 5 connection, but you can expect this to reliably max out any device you'll ever buy and beat any cable on the market.
