For safety and convenience this adjustable blind spot mirror is a must-have. If you’ve ever complained about not being able to adjust more traditional convex mirrors once they’re stuck on your side mirror then this is the blind spot mirror is for you. While it does feature a convex mirror design, this blind spot mirror allows you to fine-tune and adjust it to meet your needs. Sometimes you need a wider angle for towing or maybe a narrower one for city driving. This adjustable blind spot mirror gives you the best of both worlds! Because it’s adjustable, this rectangular convex mirror gives you up to a 50% greater view of blind spots than more traditional blind spot mirrors with less distortion. Measuring only 1-3/8 inches by 2-1/4 inches, it won’t take up too much space on your side view mirror and the black plastic housing is rust and corrosion resistant. And installation is a breeze! Just clean and dry the location where you want to install the adjustable blind spot mirror, peel the paper backing off the blind spot mirror’s adhesive pad and stick it in place with the high side of the mirror closest to your vehicle. You’re done! Even if you don’t tow or haul with your vehicle, the added safety as well as the neck-saving convenience of this wide-angle, adjustable blind spot mirror makes it a great investment. Get one for each side!
