## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    They work.
  

*by J***. on Reviewed in the United States on November 9, 2022*

There's really not much to say about these except to say that they fit my Elkhart vintage Conn 88-H trombone perfectly.  I didn't even need to trim them for the rotor index marks to line up.  The price seems a bit excessive for two tiny pieces of neoprene but the purchase was convenient.  I'm glad I got 'em.

### ⭐⭐⭐⭐⭐ 







  
  
    Works for a Conn 9D
  

*by A***R on Reviewed in the United States on October 2, 2022*

I had to shave it down a bit for my Conn 9D but it works.

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect original replacement item
  

*by A***R on Reviewed in the United States on January 20, 2022*

This is one of those very specialized items that when you need one , there isn't a substitute .  Over time , these tend to compress some and can cause the valve not to properly align , causing a stuffy or faulty tone.And if one should pop out and you lose it , about the only thing that might work is a piece of wooden doweling ---which would not cushion as well or be as quiet.  Like valve string (if your model works with string ) it's good to have these items on hand just in case.
