Second Generation ring doorbell pro, is there a big difference from the original doorbell pro

Second generation has a heat sink added to back of doorbell, the older model does not. The older model was a refurbished unit, for less money. Is it a mistake to use the older model? The heat sink was added by Ring for obvious reasons. Should I return it and get another second generation model?

Hi @Jay3100. As long as your Doorbell Pro is working properly and you’re not experiencing any concerns with performance, there is no need to return it and purchase a different Doorbell Pro. If you are experiencing any concerns, please let me know what’s going on and I’d be happy to help out. :slight_smile:
