Most of saxophone players complain about sticky pads, pads of the upper part of the instrument that don't last longer.
Solution?
Keep you pad clean.
This little "device" is really helpful for the purporse.
It's particulary useful for cleaning the "always closed" pads, like high D/Eb/F/F# (if you have the high F# on your instrument), G# (traditionally sticky), Ta/Tc pads, alt F#, low Eb and low C#.
Put the pad cleaner between the tone hole and the pad, close the pad firmly against the tone hole... strip the pad cleaner out: it removes the accumulated spit and the dirt.
No more sticky pads and longer life for you pads.
Can't see CONS... you just have to practice a little, then for cleaning all the "always closed pads" you take not more than 30/40 seconds.
