I ordered 2 the 2 Lettre Max once sent the same day or next day, very fast arrival with this walking and the cable seems impeccable and good quality for the little I can judge. It is not 'big' (and therefore can be bent easily) but seems well shielded effect.
Note that I received 2 times a version "SFTP", knowing that it is the degree of "shielding" which is a little above the "SSTP" (announced in the description here) of this I've read (shield = limiting other surrounding electromagnetic effects or other devices, always helpful if you have a doubt or many cables / devices).
If you ever receive a cable "UTP" (then meaning "WITHOUT armor") by another vendor, which is probably still cheaper, I think you should send it back. The reference is visible on the label received as "cat6" category that I have received, or the cable itself often. Purchase advised the seller; as long as you receive a well-SS or SF cable (TP).
