These cables are perfect - highest quality at the a most reasonable price. There is a lot of snake oil concerning cables of all kinds but you can trust Monoprice to give you exactly what is needed without any Baloney! Extremely trustworthy.
Before I started purchasing my cables from Monoprice, I would receive 25 foot cables wound tightly so when you go to use them, it's like straightening a spiral phone handset cord.. and the ends are super stiff to squeeze to remove cable from workstations. Not Monoprice's cables. These are "solid" heavy gauge (not thick plastic sheathing - real AWG!) cables. They are wound gently in generous size loops so you can open them, and go - no pig tails! The Flex Boot ends are simply the best I've found. They are snap free, but so easy to pinch or squeeze out of switch ports or workstation's nics. Now that I've used Monoprice's cables, I'm spoiled and won't purchase them from anywhere else!
PROS: Flex Boot ends & wound "loose" so cable is not bent
