I've tried Zero Glide nuts on both my Fender USA Strat and Fender Mexican Tele, and found them to be a bit finicky to get right, especially if you use the stainless steel frets, contrary to what they say on the website, I found that they didn't improve the tuning-stability of my two Fender guitars, the strings tended to go sharp or flat due to friction, I also didn't like the effect the Zero Glide frets had on the guitar's tone, I also had some difficulty with getting the individual string intonation at the 12th fret right too.
