I really recomend it, it keeps my valves lubricated for a long time, and with the 8oz bottle i have enough oil for a year.

This is a very good trumpet valve oil, i prefer it over all the ones i tried before

It's not as good as the Professional Giardinelli valve oil, but almost as good, and definitely worth the price

It's the fastest oil I've

Best oil out there IMHO

This stuff is very good oil

I give this oil a 5/5 and would recommend it to anyone and everyone!

Great Oil ,Last Along Time

In about a week, all the oil in the bottle had leaked out, got all over everything in my case, and everything smelled and was soaked in oil
