I have a wired doorbell I just installed. it is great, except for one thing: a blind spot AT my door. I first installed without the wedge, then reinstalled with the wedge. The wedge only made a minor difference. my doorbell is on the right side of the door. My eufy lock is on the left side of the door.

In the photo you can see the chair near the doorbell. basically, this means someone can come thru the far side of the porch and slink along the wall and behind the chair. Not everyone there to make mischief is trying to gain access to the home. I also will not be able to see packages at the door. This blind spot will allow people to come in from the side and steal packages at the door.
Trying to see if they have a few different wedge options available over the minimal 15°.
