Overall sentiment: positive
Customer reviews:
Great price, fast delivery. This particular mirror flushes well (not bulky like some others) with the existing side mirrors of the car making it blend in as one whole picture once you get used to looking at a convex mirror for guidance.

I believe every car should come equipped with it, or people should use them. I has prevented me from cutting people off big time, mainly when the traffic is hectic and you cannot afford to be turning your head 360 degrees!

Thank you! 
 they work great no blind spots anymore 
 Great product 
 So far so good. Very thin,  nice chrome ring on outside. They look great on my Corvette. Only negative,  and it's very small,  is that the sticky tape on the back wasn't centered,  so I had to cut them so they weren't sticking out after installation. 
 Perfect for work. I have people come up behind me all the time at work and this works like a charm. I can see people coming from a long way and it is small enough that it is not noticed as easy. I put these anywhere I need to see behind me. Perfect stickiness, holds really well 
 Great little blind spot mirrors, they work well with my small mirrors 
 Bought these for my 2010 Jeep Wrangler to adhere to the side vents when they are in the "closed" position for use with the doors off as side view mirrors.  These work great!  Attachment was easy, they clear the baffle easily when the vents are being used in the normal position. 
 Perfect size to eliminate my blind spots in my motorcycle mirrors. Simply peel and stick - bingo better and safer driving. Super price too. 
 Fit well and stay put  Maybe not as clear as others I've had. 
 Good quality product and looks great, I reorder it because I missed one of them on the road 
 I use these on my motorcycle to reduce blind spots in the mirrors. Works well for this. 
 Product arrived as promised. I have installed 2 of them & am well pleased with them. 
 Work well but should have ordered them a little bigger. 
 Good quality product with fast shipping. Sticking with mirror really good unlike some mirror that falls away 
 Metal frame, the ONLY way to go. 
 These are glass convex mirrors in a fixed thin-framed housing. Make sure the entire surface of the adhesive pad contacts your clean mirror and it won't fall off. 
 Looks and feels cheap but does the job done, and looks good on side mirrors. Love the frame less illusion, hardly noticeable. Worth the money. 
 works 
 Last long 
 Simple stick on product.  Looks good and works well except for the adhesive on the back.  One fell off after about a month.  Lost it on the freeway so it was a gonner.  Bought a replacement set but only one came in the package (supposed to be two).  I did notice there was a new type of double tape on the replacement - so hopefully this one will hold on. 
 Easy to use and fast shipping 
 I have put these on several vehicles now and like how close they sit against the stock mirrors.  I have not had any fall off, and use them every day to back the truck and jeep into a parking spot. 
 Great product,helps me even when backing up the car to see blind area clearly.. 
 Good 
 Excellent for those tight areas,  really shows the blind spots of the vehicle to you for a piece of mind while driving or parking.
