Together with the other one (La Tromba 2) are my "go to" valve oils. I tried several, those are by far the best.
Sometimes I have to play outside in very cold weather. Those two oils are the only ones that doesn't freeze or get my valves to react slow in 0 to -20 Celsius grades.
The smell is ok, not strong at all, I kind of like it. That's important if you play for long periods of time. It would be very bad to have a smelly oil that would make you sick.
