NAMCIM Thunderbolt 4 Cable (6.56 ft), USB4 Cable Support 120W Fast Charging/40Gbps Data Transfer/8K Display, USB C to USB C Cable, Intel Thunderbolt Certified for Type-C MacBooks, iPad Pro,Hub,Docking

Does not achive claimed transfer speeds.

This is a good Thunderbolt cable that works as intended. I was able to connect my monitor (via monitor KVM switch) to my laptop and all the things attached to the KVM worked. I was able to get the full monitor resolution at its top-rated refresh rate.

This cable seems to be very well made with good stress relief and flexibility at the connectors. I swapped it out with an Apple USB-C cable and had comparable transfer speeds.

The NAMCIM Thunderbolt 4 Cable is a high-performance cable that offers a wide range of capabilities for both charging and data transfer. With its 3.94ft length, it provides ample reach for most applications. The 120W fast charging capability ensures that your devices can be charged quickly and efficiently, even if they require a lot of power. The 40Gbps data transfer speed is impressive and allows for smooth and seamless data transfer, making it a great option for creative professionals who need to transfer large files.

This cable is a perfect replacement for my old thunderbolt cable. I had no issues with the cable and connectivity was perfect.

Im not sure that this is actually thunderbolt as I wasnt able to find it on the list of thunderbolt approved devices, but it does still hit the advertised 40Gbps data transfer speeds when using a usb4 nvme enclosure, so it is at least usb4. I was able to charge at 100w, but I would expect a cable at this price point to be able to do 240w (regardless of if theres any devices that can take advantage of it yet). For current device limitations, this cable is fine, but as 240w usb-c devices start to come out, this cable wont be able to do the full 240w, while others in this price point (supposedly) will.

This is heavy duty braided cable of excellent quality.

This is a quality Thunderbolt 4 cable that can yield excellent results. The cable jacket, strain relief and connectors are all very good in quality. This is also an excellent value compared to other brand named cables. No issues at all. 5 stars for quality and value.

I didnt have a specific use in mind for the NAMCIM Thunderbolt 4 cable when I ordered it beyond wanting redundancy for the cable Im currently using to connect an Intel NUC -- which is my daily-driver PC for basic productivity -- to an M32U monitor KVM. The quality of materials and construction appear good superficially but whats inside matters most, and that I cant see without rendering the cable useless, so Ill have to let performance be my guide.

This cable is pretty thick and feels quality, but its not an official TB4 cable. It does work well for my purposes of hooking into an LG monitor - I get passthrough charging and a full 4K display at 60Hz. I havent maxed out the transfer speed, so I cant speak to that. I think its a little overpriced but should hold up well for my purposes.
