The strings are holding up well after about 200 shots. I had a maintenance question and called ABB. I spoke with an employee named Tim, who was extremely personable, polite, and professional and gave me an answer to my question. With a great product and outstanding customer service like that, I think I will be sticking with ABB for all my strings and cables moving forward.
About three days and 200 shots after initial installation, and holding up great!
