I'm on my 2nd video doorbell pro due to a cracked doorbell button. I'm about to be on my 3rd due to another cracked button. I've informed Ring that my house faces west with the hot sun directly on it. I'm not sure if the sun itself is causing it to crack or a combination of the hot sun, the button staying hot, then the cold of the night cracking it. Either way, the doorbell pro is not invulnerable to the elements. If this happens again on this 3rd try, I'm going with a different model and hoping for the best. Also, even with the cracked button, normal functionality is still intact.
