When I changed my TV I also needed to get new tow mirrors; the tow type replacement for my stock Tahoe mirrors to match perfectly were over $600, that was out of the question! These are new so for the price I thought I would give them a try. I have yet to travel far with them but I am very impressed. I bought the convex and I can see around, behind, above and below my TM. They have an elastic strap just in case the suction were to fail but the beauty is since they stick (and they do stick) to your existing mirrors adjusts are a snap.
I had the "slip-on" before and the vibration was horrible and that also kept them shifting out of the proper alignment.
Just an FYI for those in need of or are looking to change and have an inexpensive option.
