This is the 3rd set of visors I've tried out, and they're the ones that will stay on my car.
I tried other sets and found quality to be lacking - plastics tended to feel flimsy or cheap (with rough edges and off colours/shades), or they were missing basic things like adhesive tape to attach them.
These look and fit perfectly - even through I usually prefer in-channel, these ones don't cause any interference with the window glass.
The plastic attachment clips are unique to the BaysonR design and give it a perfect fit.
I'd recommend installing these with the windows down and the doors closed so that you can get the front and rear doors to line up perfectly (I did mine with the doors open so the rear visor is just slightly out of alignment with the front - like 2mm off).
Don't bother with the rest - just buy from BaysonR and save yourself the hassle (especially given the price is very competitive).
