*by C***O on 24 July 2025*

Usei daddario por mais de 10 anos (Guitarra e violão). Infelizmente a qualidade é inexistente hoje. Tentei algumas outras nacionais e de fora. Sem comparação com essas cordas. Elas aguentam mãos pesadas. Demoram pra perder o brilho. Elas sequer criam marcas nos trates. Antes de comprar fiquei preocupado com a falta da reserva da mizinha. Mas pra vc estourar ela precisa se esforçar muito.
