I am the original owner.  I used all for approximately 3 months and put them aside.  I do NOT clean or polish my gear.  These cymbals are in MINT condition and sound EXACTLY as advertised:  Hihats: medium in weight, and have clear, bright, well-rounded tone. Stick articulation is tight and focused. These hats project shimmering wash, and would do well in a variety of musical applications.  The Ride: offers a clear, focused attack with a dark, warm sustain. Moderate overtones. And the Crash: Bright sound with a medium decay.  I price my gear to sell!  Thank you.
