You're welcome. I've not noticed the escape of condensation from the trumpet through the water key, but it does come out the bell after a lot of playing. That's where a little puddle could come from.

There's a trumpet forum where I asked about the WindSorb. There was a person who thought that it was a dumb idea because the person thought the WindSorb was for remedying leaky water keys. That impression was left by the description on Amazon. The part of the description on Amazon that lead to that conclusion says: "WindSorb has a built-in high performance absorber [I'd say absorption pad] that continuously absorbs spit and water *leaking* from the water key while you are playing your trumpet." It should not say leaking, and it should also not say "while you are playing." One does not open the water key to empty the condensation while simultaneously playing. The use of the word "leaking" could lead to someone thinking in terms of a defective trumpet that leaks while playing. Instead, it should say something like this: "...absorbs the condensation that you release through the water key on the trumpet tuning slide." Bottom line: don't say "leaking." You may also use the verbs drain, release, or empty. Correction offered free of charge. ;-) To correct the misunderstanding, I posted this video to the forum. WindSorb Purpose
