I bought these goggles for sub zero commuting. With a snowboard helmet, they work very well to provide eye protection and warmth. But if you need to wear a balaclava for rides that are colder than say -10, they will fog if you do not cut a bigger breathing hole over the mouth. Granted, this is an extreme usage for any goggle, but that is what I use them for and they have been fine (once I figured out how to keep them from fogging). Not everyone likes to cycle with goggles due to visibility, but these have decent sight lines. I like them enough I will use them snowboarding as well. Fit is comfortable and they feel like they are a decent quality for the relatively low price.
