Ernie Ball 2621

I think this was my first experience with Ernie Ball. And unfortunately it was not a good one. I broke three of these strings in a one day (without using the floyd rose). All fresh out the package strings from 2 different packs.
They all broke at the tuner. I've never had a problem like this with other strings. And I can't blame the tuner either since it wasn't the same string everytime.
The strings don't sound bad and they feel rather nice too but they seem to break rather easily. The low price was alluring but next time I'll be smarter.
