Agreed, I used ones like that when I had my F-150 and was always happy with them.
The ones OP linked to I never liked. The set I had made funny noises at highway speed, plus I was always afraid they were going to fall off.
On my last truck I bought after market extension mirrors off of ebay (just like the factory ones except 80% cheaper) and installed them myself. That was the best overall by far.
