    Excellent Towing Mirror

    The product is excellent quality and easy to install. The mirror holds its position very well so no readjustment needed once installed. The mirror provides a very good field of view. There are a few other brands and models that look similar but this specific brand and model (K-Source Fit System model 3891) I highly recommend.

    Towing mirror

    This is a good product for the money. It attaches to the mirror with great ease. Has a wonderful ratchet action tension strap. Has a great one button release for the strap. This will fit many different size vehicle mirrors. Has no vibration in the mirrors. The only thing I didn't like was the convex mirror. My personal preference would be a regular mirror. Now I have two mirrors on the passenger side, both being different convex mirrors of different sizes giving different views of the side and rear sight line. My opinion it doesn't show that's behind the trailer being towed.

    When nothing else will do. Does the trick.

    I was very disappointed that no one seems to make extension mirrors for my Envoy. It was good to see that your product will get me by. Thank you.

    Extension Mirror

    Great fit and very stable with the ratcheting straps! Really expand your field of vision when towing. An absolute necessity on the Chevy Colorado!

    He is mirrors work great. We have tried others and this is the most secure and highest quality. We use e6000 adhesive to attach the straps so they don't keep falling off in storage. I wish they extended from the car a little farther.
