Good... but expensive.
If you have an old Cisco that does not accept management from a USB port, you need this cable.
It's the same as the original but a bit longer, and it's very good.
The DB9 port is of good quality, it's not cheap like the ones sold on A***** or ***express, there is no surprise, it's quality (on the other hand, it's for a PRO use).
Only one negative point: the price
But well... I had no choice for my use and it avoided me to change my equipment... so on the whole, it's positive.
LDLC saved my week again with this product.
