I use these string in my electric guitars since 4 years ago , I gig currently 6 nights per week and after trying most of all the respected brands all I can say is Rotosound is the best deal.
No tuning issues , good durability and stability , amazing tone , affordable price , and I can't remember the last time a broke a string (I can't say the same with those other "fancy" brands that I've tried in the past).
Try it for yourself , it wouldn't hurt your wallet that much and I'm pretty sure you will not regret it.
