Review on SadoTech Wireless Doorbell for Home - Long Range Wireless Door Bell with LED Flash, 2 Push Buttons + 1 Receiver, Battery Operated, Matte Black by Rick Malloy

This thing has so far worked out great. I have the bell plugged in on the 2nd floor on one side of the house, and a button on the outside on the 1st floor on the other side of the house. For good measure I also tried it on the 3rd floor just to see the range and was not disappointed. I finally got my husband to install the button after he missed an important package while I was working from home. I can't hear door knocking from my office on the 2nd floor. Don't get me wrong, I could have done it myself because double sided tape isn't the most difficult thing to install, but I live in the northeast and this winter has had some brutal temperatures. Still works in those crazy bone chilling temps btw. Docked one star because of 2 reasons. I wish it was a bit louder because I could see me missing the bell if I'm on the first floor with the surround sound on loudly. Even if it was louder it would probably be overly loud for those on the 2nd floor which could easily be resolved if the buttons worked to multiple bells so I could put one on each floor. Well I can't say easily because I don't know what it would take for the manufacturer to make it work. But if they could I would give this 5+ stars. For now I'm happy to not miss someone at my door because of my inability to hear knocking from my office.Update: I moved it to the first floor because we missed the doorbell while watching TV with it being on the 2nd floor. I see the seller has met my wish to make 2 bells and 2 buttons. I will be investing in that instead since I can only hear the bell on the floor that the noise is on.
