I was very pleased that this site offers these kits, and at such a reasonable price. They came quickly and went on without a hitch. I am not happy that I needed them though... my helmet took a small drop onto a carpeted area and it broke the ratcheting system. So... I like the helmet fit, but it doesn't seem as durable as it should be. Luckily this site offers replacement parts!
