Reviews are mixed, some say they clog easily with mud.
Those who are used to the traditional 4-5 point fixed harnesses say they take a while to get used to because they let you move around freely until there is a jolt or sudden change of some sort (like automotive). So it feels like your not belted in until you need they, that's the theory anyway. On the upside reaching stuff on the dash or glove box while clicked in is allot easier! Lol
