I installed this on an old Alvarez acoustic that used to belong to my Dad. The strings had started to buzz badly and the bridge height was maxed out so I knew it must be the nut. Took about an hour to cut down the new nut and shape with the Drexel tool; sided/polished the frets and installed glide nut with the tallest feet wire. Worked like a charm and no more buzzing. Even lowed the bridge down to a reasonable height as well. Great product and easy to install.

I bought the mandolin version and fitted it to my Gibson. There's a lot of extra material to remove, but the result was great. Easier tuning (the old nut had tight slots for the A strings), better intonation. Later I used one of the extra frets in the package to fix a tenor guitar. For that, I simply filed the necessary ledges in the existing nut and widened the string slots. It would be nice if Stew-Mac would also sell the offset tang frets separately, for retrofitting to an existing nut.

The bone nut was easy to install. I sanded the length and depth with a table sander. The instructions are complete and easy to follow. Four zero frets of different sizes are included in the banjo kit--you try the smallest and work your way up until you have no open string buzz. Use medium viscosity cyanoacrylate (available from Stewmac) so you have time to set the nut and fret properly. I'm pleased with the results, improved tone, and hammer-ons and pull-offs are more defined.
