I like my K1 - HONIG'S PRO ELITE PROTECTOR, however Friday I took a 90mph foul ball off of my collarbone and it hurt! The impact caused my necklace to cut my skin. I also broke the clasp on my necklace. I have to say that if I had my old protector on it would have broken my collarbone. You can check the K1 out at
