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.

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 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 youVibration: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.

I haven't used them yet but will be in two weeks. I have attached them to my mirrors and they attach nice and neatly. I can still use the original mirrors and these give me the view behind my trailer I need. They are nice and solid and do not shift around. They are a bit stiff to adjust but that is because they are new and will loosen a bit as they are used. They need to be stiff to stay in position so hopefully they don't loosen too much. For now I am happy but will know more better after my travelling this summer.

Mirrors fit my BMWX5 perfectly. Due to the pandemic have been unable to use them with the caravan attached however have tried them out whilst driving the car on it’s own. Mirrors did not come loose or vibrate, so far looking like a winner.

I was very concerned about vibration and poor quality strap that I’ve seen from other manufacturers and damaging the painted surface. Also surprisingly to me, Jeep offers no aftermarket mirror extensions.-the rubber blocks and strap ratchet tightly and are very secure. ☑️- reasonably straight forward installation ☑️-very minimal vibration ☑️-adjustable so it works well will the slightly odd shape of the mirror housing ☑️Worked above my expectations and would definitely recommend for SUV use.If I could change 1 thing, it would be great if they had longer arms available to extend the a mirrors out a bit further.

We got them so we can improve visibility while towing our new caravan. They should do the job. A bit fidgety to install but fit tightly.

Good quality but difficult to hold all the components/pieces together from falling apart to the ground before enough ratcheting tension prevents loose strap connecting points from easily undoing (4 strap connectors are a weak click-together design). Too much time/finnesse to get it to piggy-back onto my nissan frontier mirror body while straps threaten to disconnect; but once tightened in place, they work great! I have a chunky hockey puck shaped blind-spot sensor that helps stop straps from vibrating off while driving. If you don't have a bulky sensor housing at the end of your factory mirrors, these mirrors would slowly slide off sideways while driving if your side mirrors taper outword like cat eyes ( like my nissan frontier has). They vibrate a wee bit while driving on expressway, over bumps, etc... but you can still see vehicles clearly dispite minor wobbling. I'd buy them again if lost or stolen.
