Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this K-Source 3 3/4 inch round, stick-on, blind spot convex mirror. It's for a quantity of one. Now, this round spotter mirror will attach to your factory side view mirrors to reduce blind spots when you drive. This is a nice convex lens, which provides a wide angle view, so it'll increase visibility for passing or changing lanes.
It is a nice, sturdy, corrosion-resistant black plastic housing. And if you notice it has this nice, simple peel and stick installation that you install it onto your factory side view mirror. Few specs on this, it's for a quantity of one spotter mirror. And we mentioned the diameter of it, one end to the other is right at 3 3/4 inches. But that should do it for the review on the K-Source 3 3/4 inch round, stick-on, blind spot convex mirror for a quantity of one..
