Lost stylus seeking similar experience

I've used STYLAST on many carts over the years.  Never an issue.  I was also one of the very first LAST dealers and sold a lot of it.  Never a complaint...

I bought a Supex 500 mc cartridge with a missing diamond. The cantilever and suspension is intact. It awaits a replacement diamond.

I believe Steve is correct, the adhesive got dissolved, the tip simply fell out.

It happened to me, on a rebuilt cantilever/stylus, one day the stylus was gone. I used liquid stylus cleaner frequently on all my cartridges then.

It happened to my friend's Benz Micro Ruby Wood, Steve was able to put a new MicroRidge in the existing hole in the cantilever, glue it, and put a warning not to use liquid stylus cleaner on it.

Steve just repaired another friend's Grace F9 Soundsmith replacement stylus and warned my friend not to use liquid stylus cleaner.

Had a stylus fall off midway through an Lp. 
Dynavector XX2MKII that I had bought from a guy in Asia who used to list cartridges often here on Audiogon. It only had 100 hrs playing and no warranty so just did the factory rebuild and lesson learned.
