I have had it for four months, it has not experienced anything. Very good construction, excellent for its price and without any loss of speed

The product we are talking about is amazing & something else!
First of all, it comes in a nice transparent packaging, so you can see what it contains, with a nice opening, without the cable being damaged. Then, as soon as you touch it, you realize that it is a serious construction, and not the type that costs 0.5 €/m. It easily detaches from the hooks and can be easily spread in any room, from the living room and lounge, to the kitchen and bedroom, truly presentable, discreet, and absolutely functional! The connection is made with certified 3rd Generation Ethernet plugs, which fit well, so the data does not leak left-right and outside the sockets like other cables. Also, the speed...reaches Super Satisfactory speeds, suitable for both downloading and uploading, in the range of 100+ Mbps! What else can I say? Congratulations!

There is no loss up to 10 meters... From there and above, generally, there are losses according to what I read, so I didn't take the risk.

I did not notice any losses in connection despite it being quite long. The duration of use we had was short, so I do not have an opinion on durability over time.

Honest cable, does what it says without any loss of speed. Highly recommended. Been using it for two weeks without any issues.

I didn't know that Cosmote provided such cheap cables that would give me a difference of 0.5 MBps with this cable

It does its job perfectly fine for now. I liked that it is black and not gray like all the other ugly ones, especially when it is spread out inside the house.
