This product gets a 4 due to how quick they seemed to fade. I bought the Ibanez FRIX7 and purchased 3 packs of these to try them out.
At first I thought they were amazing, then after about a week I was kind of hearing less tone and it sort of kept declining from there. FYI I have extremely acidic fingers so it’s no surprise that I had this issue. It definitely last 2-3 times longer than a D Adarios so the tech does work. That said, I ended up buying heavy Elixers and using the low string from the packs of EBalls. Sounds awesome and works the way I need.
Hope this helps!
