CalDigit [Intel Certified Thunderbolt 4 Cable - 40Gbps 100W Charging, Compatible with Thunderbolt 3 & USB-C, 2016+ MacBook Pro, Air, 2020+ M1 (0.8 Meter 2.62 Feet, Thunderbolt 4 / USB 4 Cable) Laptop

I needed a longer cable to connect my Mac Studio to the Studio Display and as this was on a discount I bought it. The Apple version is way too expensive, I don’t attach anything to the monitor and basically it does the job perfectly.

This is a great cable. It is one of only a handful of cables to support full Thunderbolt 3 at 40Gbps, 100W of charging power, and long lengths of up to two metres. As listed in the description, this cable does *not* support USB 3, because it is an "active" cable - a necessity for Thunderbolt 3 cables longer than half a metre. The other reviewers seemed to expect USB 3 support. I've tested it with an LG UltraFine 5K display and it works perfectly. It can also be used as a charging cable. My only criticisms would be that the branding on the cable ends is ugly and unnecessary, and it would be nice for the Thunderbolt logo to be whiter rather than the yellowish off-white that it is; it looks quite cheap when plugged into a MacBook Pro next to the Thunderbolt 3 cable LG provides for its UltraFine 5K display - see pictures.

I use this with Thunderbolt 3 devices such as external SSD storage and video capture devices by BlackMagic and it has never failed. I have other TB cables which are TB3 and have had issues. I’m not saying that just because this is TB4 it makes it better than TB3 cables for TB3 devices but it is definitely the most reliable cable I have. I use this on a MacBook Pro M1 Max, which has TB4 ports. Maybe it’s the combination of the Mac’s ports with this cable that make it so reliable? I don’t know. However, the combination is perfect. I also use it with a couple of USB C SSDs and it’s flawless. Without a shadow of a doubt I would recommend this cable, it just works.

Used on a Dell XPS 13 9380 laptop to connect to a Razer Core X e-GPU containing a nVidia 1060 graphics card. The (passive) cable that comes with the enclosure means that you'd need to have the enclosure right next to the laptop, with its' fans running close to where you're sitting. Using this cable you can have it on the floor tucked out of the way - both visually and in terms of the noise - and I've experienced no trouble whatsoever with this setup. Yes - as mentioned in other reviews - the plugs get slightly warm, but that's because they have heat generating components inside - and they've certainly never got too hot to touch. Expensive for what seems to be just a cable - but worth it.

Purchased to connect M1 Macbook Air and Razer Blade Pro laptops to a 4k HDR 10-bit colour 144 Hz monitor. It has done this flawlessly in both cases, and has been much more reliable than an HDMI 2.1 connection with the Razer. It has also reliably charged the Macbook via the monitor. The length has been very useful and allowed greater flexibility with positioning of devices relative to the monitor. The cable management with this is also made easier by the soft-feeling flexibility of this Caldigit cable. It is much more flexible, practical, and reliable than the HDMI cable that came with the monitor. Overall, I am pleased with the performance and quality. It could be that the price reflects the cost of producing an active Thunderbolt 4 cable, but it does feel very expensive for what it is - hence my overall rating of four stars (I would have given it four and a half stars if I could have).

Purchased to connect an elgato hd60 s to laptop, the hd60s is type c and because its a capture card it needed something heavy duty like the one provided by elgato, the problem is the market is overflowing with cheap cables everywhere. So I thought I'd give this one a try. Safe to say that it's upto to the task and performs exceptionally well for its intended purpose. In the meantime I've also used it to charge phones & tablets also I've used it to send audio from a Sony smartphone to a fiio portable dac and it works flawlessly. It's quite thick so feels very durable. Would I recommend yes but it all depends on your intended purpose. It is after all a Thunderbolt 4 cable and not your average type c cable. Would I buy again? Definitely although this time round I will go for the longer length even though its well beyond what I'd comfortably pay for a cable.

A fantastic quality cable with great value for money. The cable length is perfect for connecting something a little further away (or mounting a dock under your desk as I did). Have purchased multiple of these cables and wouldn’t hesitate to buy again!

Reviewing cables is like pulling teeth, only more painful. What I can say is that these have decent build quality, perform as expected from a CalDigit product (I have a CalDigit T4 hub) but a shame that they cost so much. That said, better value than much of the competition in this market.
