Fit System 3891 Deluxe Universal Clip-on Trailer Towing Mirror

I just used these on a 1,200 mile trip picking up a small camper. I'm happy with their performance but here's a list of things I found important: - The mirrors are convex so the image they produce is smaller than the regular mirror on the drivers side and about the same as the one on the passenger side. This wasn't a problem for me - I liked the extra view but had to remind myself of the difference when backing up. I've attached an image to show the view they provide. - I have a Toyota 4Runner and the factory mirrors are tapered, getting thinner as you measure from inside to outside. These mirrors attached fine and held pretty well. They did gradually work their way towards the outer edge. It became noticeable after about 700 miles so I pulled over and reinstalled them. In the future I'm planning to place some silver duct tape on the factory mirror frame next to the inside strap clamp so as soon as the mirror starts to slip towards the outside there will be a gap between the tape and the mirror mount. - when installed I found one time the clamp that grabs the edge of the factory mirror wasn't properly gripping the frame even though when I had started it was properly in place. This means as I was adjusting the straps and tightening the ratchets it popped off. Just something to be aware of. Not a product flaw, just my inattention. - I expected them to work their way loose so I put a sturdy velcro strap around the base of my factory mirrors and then used zip ties to attach the mirrors to the strap. I figure if one did fall off I at least wouldn't loose it though I could end up dinging the paint on my 4Runner..... - My girlfirend is going to help me modify a velcro strap to secure the inner ratchet strap to the inside edge of the factory mirror frame. I'm thinking this may prevent the mirror creeping out and falling off. To sum this up - these mirrors worked great and allowed me to see around a wider camper. They need to be checked regularly just like you would check the hitch and lites regularly. Simple enough and I don't think I'll ever loose one, but if I do I'd be happy to get another one of these to replace it.

I'm towing a 23' Forest River Ozark travel trailer with a 2018 Tacoma TRD Pro. I needed mirror extenders to see around the trailer but did not want permanent towing mirrors. These mirrors do work and met my needs at a budget friendly price. I noticed that you need to read the instructions and attach the mirrors as they explain or they will viberate some when driving. I set one up correctly and the other I did not, one wiggled while driving and the other didn't. It was important to keep the rubber block with the ratcheting mechanism in the center of the mirror you are attaching to ...that made the difference for me. They attached easily to my stock tacoma mirrors and left no damange or marks as far as I can tell when removed. The mirrors were very tight in their ball socket, making it a little hard to adjust, however I also think that makes these mirrors move amd viberate far less than others when driving. My only real complaint, price and all considered..... I wish they packaged these mirrors in packs of two....they are sold individually. They could be nicer, but then they would be more expensive and we all would complain more 😀 This is a good mix between quality, price, and functinality ...a sweet spot for someone in my circumstance.

I recently purchased 2 of these for use with my Xterra and I am very happy with them. I only have one trip under my belt using them but the last set of mirrors I purchased were returned before the trip, so... I previously borrowed a family members Milenco Aero 2 towing mirror and I really liked those. Their no strap design was quite slick and worked well. That being said buying 2 of the Fit System 3891 towing mirrors is still less then just one of the Milenco mirrors. So whats the difference? Attachment Method: Milenco wins. It is just so simple to clamp on and go. The Fit System ratchet straps worked just fine and held great on my Xterra. They do take a bit more time to get setup and adjusted. What you can see: Tie. Both have a great view and are large enough to see whats going on behind you Vibration: Fit Systems wins. There was hardly any vibration when towing. The Milenco mirrors weren't bad but the Fit Systems mirrors were noticeably more stable. Price: Fit Systems - Enough said... Overall I think the Fit Systems mirrors are great and I am happy with my purchase.

We recently bought a 2015 F150 and a travel trailer camper. Unfortunately we were unable to find an F150 in the style we wanted that came with the telescoping mirrors so we figured we'd find them aftermarket. Well, since the new F150 is a new redesign, it turns out that aftermarket manufacturers have not designed mirrors for this new model yet. So after combing through the internet we settled on this Fit System Universal mirrors. We have not been disappointed. We recently got back from a 1500 mile round trip and the mirrors performed very well. It took a few minutes to figure out how to tighten and release them, but once we got that under our belts, it was very easy to get them on and off. They fit very securely and we never had a problem with the loosening or vibrating, even at 75 mph on the Interstate while passing semis. I have seen some reviews where folks have said that the straps have broken. I can see this happening if you overtighten them. The mirrors use a ratcheting system to tighten the straps. The should be tightened until they are secure. The straps are plastic. Even though they appear to be plenty strong, the ratcheting system is easily strong enough to snap the straps if you get overzealous. I suggest that once you get the straps in place, ratchet a couple of times and test for a snug feel. Once they are snug, leave them alone and they should hold very well. Great deal the price. I highly recommend them.

PRODUCT UPDATE!! As many other people have stated on reviews - this will fall off at some point at even moderate speeds! I loved this mirror for the period of time I had the first one. After about 5 uses - this slid right off of my mirror and got crushed going ONLY 35mph!! It DOES NOT tighten very well for it to not just slide or slip off the end of the mirror in heavy winds or warm temperatures. I believe the biggest issue with this mirror is that the rubber straps are easily bendable or stretchy when the temperatures outside are above 90 degrees. The rubber is not very solid and is too pliable in warm temps. for it not to start stretching after putting this on very tightly on the mirrors. I think because of this mine and many others have slid right off the mirror. Also, I also believe that these mirrors need another strap that holds it on horizontally to something, rather than just the 2 vertical straps that wrap around the mirror. I purchased another one as a I do like this mirror, but it has a major flaw (maybe more specific to Tacoma mirrors?0 that causes it to easily slide off. I NOW strap this on with 2 small bungee cords that now don't allow it to slide off the end of the mirror in warm temps or high winds/fast speeds. I have these 2 bungee cords wrapped around the inside of the mirror and onto the small open slots that the straps are hooked through. With this setup I have had NO issues with it even slipping or moving AT ALL. It keeps it tight and is very easy to put on and remove when needed. I was able to drive in wind and rain with this setup going 70 mph and a really strong 30mph wind in Oklahoma plains with this setup and didn't have any issues or fears of it sliding off. Previous review - before it fell off and broke at 35mph: Great fit on a '12 Tacoma. Easy to strap onto the mirror and holds tight. I've used it on several trips and this thing is way better than anything else I've tried. Doesn't vibrate too much and lets me see behind my TT now. The visibility is great with my Jayco 174 TT.

We pull a small camper with our Jeep Grand Cherokee and felt we needed better mirrors for safety. This mirror works perfectly for our needs. Now we can keep an better eye on who's behind or coming around us. Unlike cheaper strap-on tow mirrors, this one features ratchets so you can adjust the fit quite well and keep the mirror in place much more securely. We always check the fit when we stop and should it need tightening it is so easy to do without removing all the straps. When you are ready to remove the mirror there's a quick release feature so that they come right off. The Just be sure to store them in a bag or box because there's a small strap that could get lost if you don't take care. We are very happy with this tow mirror and have already recommended it to some of our camping friends.

I installed these mirrors (2 qty, as they are sold in single units) on a 2012 Toyota Highlander to help tow a 21' travel trailer. They greatly improve the visibility of the sides of the trailer, though in my case, do not extend away from the vehicle far enough to provide "perfect" visibility. My trailer is 8' wide, and I still have a slight blind spot toward the very rear of the trailer. This may just be par-for-the-course for temporary mirrors, however. The mirrors attach easily, though it took some trial-and-error, as the directions are quite minimalist. Note that to properly tighten the straps, you ratchet them with a little lever/handle on the straps before closing the lock shut. The mirrors themselves are very difficult to tilt the way you want them, but that's a double-edged sword, as you don't want them jiggling out of place when going down the road. Once tightened and adjusted, they work great, and stay in place.

This mirror set is great and goes above my desires and expectations. This is my third attempt at deciding on a mirror towing extension. The first one interfered with my side mirrors. The second try was better but going above 45 mph the mirrors vibrated so much so that they were unusable. This third one is great, easy to put on with the ratchet straps and very stable. I wish I had purchased this one first! Thank you for your excellent customer service policy.
