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.

It does not corrode the valves at all, as some of the lower-end brands do, and it gives a very fast valve action to the trumpet

Eliminated a sticking valve problem that bothered me for years

Probably the best valve out there for the money!

They have sticky valves in there trumpets and have since new.

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

Blue juice valve oil is the BEST.

They have sticky valves in there trumpets and have since new.

Fixed my son's sticky valve problem

This is the best valve oil
