The last time I bought swimming goggles was probably 1992, so I was a bit leery of these goggles at their relatively low price point. They fit great, and they don't leak much at all. I exert myself pretty hard when I swim (i.e., I am out of shape), and they don't seem to fog up very badly. Every now and then I need to de-fog them, but mostly they're great. They stay in place, they don't leak, and they're adjustable. I particularly like that adjusting them is not particularly easy to do -- yes, I like that it's hard to adjust the length, because that makes the length very stable and secure. They're good goggles, particularly if it's been 20+ years since you've bought goggles.
