If you are an avid road cyclist, this product is a must-have for your safety, and it is a quality investment. It has high engineering functionality and a great design.

Great glasses. Rear view mirror not so much. Moves around when you ride.

I'm returning these after one use because the mirror's visibility is extremely poor. I have ridden with a helmet visor mirror for 40 years and I was hoping this would be better, but it isn't.Pros: Comfortable design, especially on the nose piece, and the glasses are very light. Lenses filter UV light well. Glasses come in a very fancy case. Mirror is easy to adjust.Cons: It's very hard to get the mirror to show you what's behind you (!). The best you can do is fix it so that you have to turn your head 60 or 70 degrees to see the road behind you, and even then the mirror is too small and poorly placed to allow you to see what kind of vehicle is coming and how fast. My visor mirror does that easily. At night, you can't see much of anything except lights.I used these glasses once and was almost hit from behind by a car I couldn't see until the last second. If the mirror were placed higher and if it was a bit larger, it might work, but for now I'm sticking to my old one.

Excellent product. Careful patient adjusting then they are great 👍

I love these glasses, they appear to be very high quality , they feel good and fit good, the rearview mirror is a game changer for me.I now feel safe enough to ride with my earbuds and play my music, before I was too nervous to play music because I couldn't hear approaching traffic. Now a quick glance and I'm good,They take a minute to get used to but once you do, they're great.

I was initially hesitant to purchase this item because it was flagged as “frequently returned.” But after considering other options and seeing a number of positive reviews and detailed videos I decided to give them a try and I’m glad I did. They work great! It didn’t take long to get the mirror adjusted just right and now I can easily see behind me. The quality is excellent.

I could never get those rearview mirrors that attached to our helmet to work. I finally found this and for me it works perfectly. You do have to play with it a bit to get it adjusted correctly and you have to develop a little technique to tilt your head to check rearview traffic. But the transition lenses are fabulous and the rearview mirror works as advertised and I’ll never go bicycling again without wearing these glasses.
