I tried to like these, even bought 2 sets for both my teles. My d string broke but that was my fault as I installed the saddle backwards. Customer service had asked for a photo of my setup and I sent it to them and they pointed out my error. But then the b string broke after only about an hour or so of playing, and that was with D’Addario NYXL strings, which are supposed to be quite durable. I contacted them again and they promptly sent me a replacement saddle. Well, I installed the new saddle and switched to Ernie Ball Paradigm strings, another string set that is supposed to be durable. And guess what - the b string lasted about 12 hours or so of playing and broke again. Now I have another set that I will not be installing on my other tele. Oh well.
