I have owned a Yahmaha trumpet for 20 years. Its a great horn but the valves were always sticking no matter what oil I used. Now with the Alisyn Oil, that's all changed. The valves work flawlessly. This oil is just great stuff.

Don't let the size fool you. This stuff is great; the best valve oil I've used. Only a few drops can last weeks! I wish it came in bigger bottles. I made the big mistake of buying and 8oz bottle of another brand of valve oil so I had more plenty of valve oil in stock- but believe me; in this case more ISN'T better because the other brand I used sucked! I thought something was wrong with my valves or my trumpet. I decided to switch back to Alisyn and it worked immediately. It's effects were immediate and I was playing quickly and efficiently. This stuff is great for all trumpet players.
