The Combo 910 arrived and I have strung rackets - everything works perfectly. I went on \"stringforum.com\" and posted a very positive review of your Combo 910 stringer and your company\'s service last week. It has been 7 days and they still haven\'t posted it to their Review Section. It doesn\'t look like they play fairly. I\'d be more than willing to be a reference if you need one in the Boston area.
