I ordered some Quadratec Adventure mirrors back in July. Reviews for them weren't that great-basically I assume they're going to rotate out of place with the wind; I just wanted something cheap as I probably won't go doors-off that often, or drive at highway speeds with the doors off. Or if I eventually decide to shell out for tube doors I'll get some real mirrors to mount to them.
Didn't notice they were out of stock. Now that it's well past doors-off season in northern Maine, they finally shipped today! Guess I'll try them out next May. Or maybe I'll take the doors off for a day and put on my snowmobile suit on!
