How is your experience ordering the 1l bottles in terms of shipping times? Are they over/underfilled ? I am considering ordering some and would like to hear your own experience.
I am not complaining really, as price was outstanding as is testing generally with my past orders with QSC. QSC is not perfect, nor is anyone, but they have always been fair with me overall.
