A relatively thin and flexible cable

I increased my download speed fivefold (100 Mbit/s) and my upload speed sixfold (400 Mbit/s) compared to my unstable Wi-Fi (20 Mbit/s — 60 Mbit/s). The only slight drawback for those like me who have to run the cable along a skirting board is that there are markings along the cable (like many RJ45 cables). But you can easily hide them by placing them on the skirting board/wall side.

Nothing to report

Seems sturdy and perfectly matches the product description. Category 8.1 is far superior to my needs, so it's difficult to judge the speeds.

Excellent

My current favourite network cable. Best reserved for fixed installations (rack, cable duct, patch) given the very thin plastic protective sheath. A price/performance ratio that I find more than acceptable.

Excellent

My current favourite network cable. Best suited for fixed installations (rack, cable duct, patch) given its small diameter, which is mainly due to the very thin plastic protective sheath. I think it offers excellent value for money.

Very good RJ45 cable. The speed is there, and this slim cable allows you to run it discreetly anywhere.

Very well

Very flexible cable, so very easy to handle.
I use it to connect my box to my electricity meter's Ethernet ports. My PC reaches 4200 Mbps in speed tests.
Ideal for home use.
I recommend it.

Perfect for home use.

It's thin and flexible, perfect for management cables. It offers the same performance as a traditional Ethernet cable. I was sceptical because of its thinness, but I have no regrets.

Perfect for home use

They're incredibly thin compared to traditional Ethernet cables. The ferrule is a little small, although this is not a problem when removing it from a computer or Ethernet switch. They are very easy to place, as they are more flexible than traditional Ethernet cables. At this price, it's well worth it.

Thank you Orange...

Newly connected to fibre, I used Wifi to connect my office PC to the box (1.2Gb/s which is very good, CM and Box in Wifi 7).
I ordered this cable to get more speed, as 2 Gb/s is available at the box.
When I received it, I did a flying test, but to my surprise I was still below 1Gb/s speed.
With the help of technical support, the problem was found, it comes from the LiveBox S which has 1Gb/s RJ45 ports.
So there's no point in using Ethernet, I'm sticking with WiFi.
Returned the cable in its original packaging.
Refunded quickly.
Thanks to all the teams.

CLEAR

In fact, the wire is thinner and more flexible than the standard models we've seen to date. What about mechanical strength? To be seen over time.

all-purpose

I needed to pass against an external door sill. An ordinary cable was too big. With this slim cable, it's stuck flush to the ground and remains very discreet. Ideal

Almost perfect

The cable is very flexible and very thin, making it ideal for running along a skirting board while remaining unobtrusive.
The only drawback is that their shielding level is low, so there's a noticeable loss of throughput if the cable is "mixed" with power cables. In my case, I had to route the RJ45 outside the trunking where I have all the PC power supplies (PCs, monitors, speakers, accessories), otherwise I'd lose more than half the throughput.

Very good cable

Perfect 0.5m cable, not easy to find, higher category, problem-free connection. Very good value for money. Same opinion on the 1.5m cables I bought.

Slow flow

The product arrived within a reasonable time and in good condition. It was long enough for my needs. Only the internet speed is not improved by using this ethernet cable. I wanted this to be the case, so I'd try an aluminium tip at the end of the plug-in. In the meantime, it hasn't had the desired effect.

Good ethernet cable, thin and discreet

I'm completely satisfied with this cable as part of a renovation project. I was looking for a high-performance, discreet cable.
And what's more, they are located in St Grégoire, where they offer a warm welcome, advice and delivery of the product. Very good service, good advice and delivery of the product.
