I purchased this to replace our old doorbell system that failed.We use it for our business lobby outside of a remote locked door. So far it has worked perfectly. The door bell is very easy to hear and the push to talk is crystal clear. Very happy with the purchase.I've only had it installed for a week so I'm unsure if the Solar charger is working. I will know in a couple of weeks.I will update this review in a couple month.
