U1 difference questions.

How big are the differences in the quality between, Lena, Jason and Michael Travis. Are their U1s noticeably different? I just bought 2 U1 datejust from Lena and the bands quite frankly feel like dogshit. Is that the theme between them all? I come from building seiko mods so I guess I just expected them to be similar to those metal bands but I guess not.
