I run an evotech. I like it the only problem I've found with it is that the holes are just big enough to let little pebbles in and not out. Easy solution tho used metal bug screen and a combination of 2 sided tape and spray glue on the inside of the guard. Has held up for a season so far and is actually easier to clean due to less bug guts making it onto the cooler. Haven't even looket at the cox cooler guard so no opinion on it at all.
