I have now used these strings for about 10+ years. Love them for the level of control and forgiveness to tennis elbow issues. It usually last me about 6 months of play.
First, I think the strings played well for me, not a hard hitter ay 71 yo. BUT, the string Broke after 12 hours of play ! Sorry, that is an awful short time. Never in my tennis life have I had a string break anywhere near that short of time. The good news, MIDWEST has reinbursed me with a New set of Strings ( the same). -Ron M.
