What is your opinion of this product?
I have been playing these strings for about 10 years now. I have never had one break. The only issue I have ever had was the ball end unwinding on the high e string. But, that was on a jaguar. Seems to be a common problem with the jag/jazz tremolo, with any strings. I will continue using these as long as I play. I usually get the 12's for my jazzmaster, 13's for my jaguar, and 11's for everything else. I highly recommend these strings.
