Are you talking about the convex mirror in the top left corner of your drivers side mirror?

If your talking about the little blind spot mirror. Give it time you will love it.
I find it helps a lot.

wait, they make one with the convex mirror on the passenger side?

If the convex is what hes talking about..I love mine! its awesome. Oh and the passenger side one is one BIG convex mirror...the whole mirror is curved if anyone has noticed that.

I didn't notice that at all.

Yes, I've seen a few F150s with that little passing mirror on the passengers side. I was thinking about buying one but didn't know the part number.

Take a straight edge to it and you'll notice

Well whadayouknow!!! Still wish it was like the driver side

It may be because you don't have your mirrors adjusted properly.

When properly adjusted, you shouldn't be able to see the side of your truck.
