Good range, reads temp AND humidity for outdoor channels. Works as advertised. The antenna broke easily, as it is just crimped on. Otherwise excellent.
Know the temperature before you step out!!

We owned the indoor/outdoor thermometer/hygrometer for the past 5 years. When the remote broke down due to weather, I am sure, we just keep looking for the reading that isn't there. So we wouldn't be without one now.
Thank you for your efficiency in getting a new device to us. Your service has been exceptional.
