A minor gripe: the little rubber buds slip off sometimes and I have lost them before while they were dangling around my neck, thats pretty annoying because generally one size of the sets given to you fits way better than the others. I will be taking it to Mexico in a few days and will be using it a lot. So I know that people do complain about Amazon taking over the world the simple fact is they have access to the world and so these fit flops came from a seller abroad. Very narrow please size up Im very impressed with this product! It doesnt turn as loud as Id like them to but thats probably because I listen to everything at a way too loud of a volume. Thats because once you see you first spider like alien youre going to freak out a little. I buy a pair of sambas at least once a year for years and years. We love the Burt?s Bees footie pajamas because they?re soft and their prints are the cutest BUT their sizing is so inconsistent. My son has tries them out & would now like a pair too!
