Are guess sunglasses good or bad?

i bought guess sunglasses today from sunglass hut. they were about $80 and made in china. i saw some other sunglasses, made my a different brand that were made in italy..but they were like $200. the guess ones fit me perfectly so i bought them. i was wondering, are they good or not? and are they genuine? it does have the little European CE mark..but i was still wondering
