K-Source Snap & Zap Custom Towing Mirrors - Snap On - Driver and Passenger Side
The KS81600 (pair) snap-on mirrors mounted quickly and fit snug and beautifully to my 1999 Ford Expedition Eddie Bauer Series with contoured mirrors, and did not impede the existing Ford mirrors whatsoever. However, I have a problem with the focal distance of the passenger side KS81600 mirror that I received. See photos. It's magnification is quite different from the truck mirror, and shows only a small, magnified area of the distant background. In contrast, the KS81600 driver side mirror has a similar focal distance as the Ford driver side mirror, offering more of a long and broader view. I could live with the driver side view, but not the passenger side. I'm unsure if this difference is intentional or a product error/mis-match. I've contacted the eTrailer experts on the matter. Alternately, I also ordered a pair of the KS3891 "clip-on" mirrors, with the ratchet system. While I think this product offers a much broader view on both sides of the vehicle, they are not near as easy to put on as the KS81600, never quite go on in exactly the same position, and are not a perfect fit to my contoured Ford mirrors on the passenger side. In addition, the thicker clamps of the KS3891 make contact with the Ford mirror glass and impede my ability to fully adjust them. I will post a separate review of them. The KS81600 is a much cleaner, easier product to install and secure. Unfortunately, the focal distance issue is a deal killer for me, and I'll probably keep the KS3891 which provide a broader view on both sides of my rig.
I have a 2002 f150 Lariat supercrew with the turn signals on the mirrors and these fit perfectly over them with plenty of room to still adjust the mirror. I tow a 19ft travel trailer and can now see the traffic behind me, no more hoping there is no one coming up on me as I change lanes, and the mirrors barely vibrate so you can see very clearly in them. They fit nice and snug on the truck mirror so there is no worry about them moving around or falling off. The only negative for me is the bottom clip scrapes up the truck mirror a bit every time I take them on or off, so be carefull. Overall very happy with them.
