I bought this because I needed more flexibility regarding cabinet placement in my home studio. My normal cable is a 1m high-end cable, which I use when my head and cab can be placed close together. But more often than not this is not possible and for those situations I needed greater length. I bought the Pro Snake 12544 - 3,0m because the price was so competitive compared to high-end cables. Having A/B'd my high end shorter cable with gold plated plugs etc. with this, I can sy I hear no significant difference - i.e. the added impedance from the longer cable does not rob me of any treble that I can hear.
The connections of plug and cable seem sturdy and strong and have not given me any problems so far. Great value for money.
