I'm a huge fan of the Milan by Noriko, but when I started to let my hair grow out to it's natural (gulp) grey color, I turned to this one as the Milan doesn't come in those shades. The Top secret is just as comfy and good quality good quality as the Milan, but I'm not liking the lace hairline as much but it's workable, therefore the 4 stars instead of 5. I put my toppers through much 'abuse' as I lead a very active lifestyle outdoors. This one went with me to Maui for 10 days, suffering a lot of wind and sun, surviving the ordeal just fine. I know I could've if I'd wanted to. even worn it while bobbing in the water, pinning it up with my bio hair, If I'd wanted to. I'll continue to wear the Jon Renau Top Secret until Noriko will make the Milan in greys COMMON!!! I like the larger base on the Milan and Top Secret, as it covers more and adds a bit more hair. I get a freakish amount of compliments on the color for the Top Secret, 56/51. I'm constantly approached by young women asking where they can get my hair color? We definitely need more long gray styles (I refuse to go short just because I'm older!), wigs and toppers, available in grays as this color is a total fashion statement. Get with it wig companies! PLEASE????!!!!
