I wanted a Ring Doorbell Pro but was hesitant because my doorbell button and wiring are perpendicular to the front door. I had been reading reviews on all the Ring angle mounts, and it seems like there are complaints about every one. I decided on the Kimilar and am very happy I did. The 3 pieces fit together snugly, the hardware is great (and they give you more than you need). I used all 3 to angle out the Ring Pro to 45 degrees, and it is just enough that I can see my whole front porch now. This mount has a nice big opening for the wires, the holes line up perfectly with Ring Pro, and it really does the job nicely. Using all 3 pieces and the doorbell unit, it is very snug and secure. Also, for anyone who complained about the screws - I used a power screwdriver to mount this into my door frame, and there was no stripping and nothing broke. This is a quality kit. Highly recommended.
