In general I like these a lot. Would definitely buy again. I haven't tested them for water resistance, but I've used them a few times and never had any fogging issues. I can also use my phone to take photos through the lens (not perfect and not good quality but it works). I really appreciate their compact size and also that they take up VERY little space in my backpack and can even be attached to external MOLLE loops (I modified the rear belt loop with a built in latch).
