Hi all, I'm writing to let people know about my satisfaction with my Contender, first thing is the light weight, mine weighs in at 80 grams minus lock, second is comfort, was locked in for 16 days and ZERO issues, being a SS cage that is very open in design cleaning is very easy. Mark is great to work with ( even returned my call and spoke for 20mins) . I thought of a way to make an anti-pullout ring and gave the dimensions to Mark to make, he made the ring and now I have been locked for 24 days with no problems!! Turn around was about a week on both device and custom ring. My Queen is VERY happy....enough said?
