Indoor Outdoor Thermometer Wireless 4 5 Inch Display Digital Hygrometer Thermometer Temperature Humidity Monitor with 330ft Range Sensor

After 1.5 years of continual use, it still works great! The things that impress me are: 1. Accurate temperature reading. 2. Easy to read. 3. Easy to set up. 4. Transmitters work through multiple walls. 5. Long battery life (using quality alkaline batteries). 6. Uses common battery sizes. 7. Because it's battery powered, it works during power outages. 8. After 1.5 years, the base unit and all three remote units are still working perfectly. The things I don't like: 1. The hanging hole on the remote units needs to be larger. The remote I use outdoors is hanging on a small nail, but I would like to use a larger nail because it has blown off in windstorms (and still works!!!). 2. The humidity function seems to be iffy on two of the remotes. They're not off by a lot, but they're not accurate. Overall, I'm very happy with this product and I would definitely buy it again.

Works as advertised, replacing a unit from another mfr that failed when temps dropped below 0 F. Have not reached that point. With three remote units, we can track temp variation in rooms away from the thermostat location, as well as outside. Setup was easy. Also measures humidity. Base unit comes with a USB cable to light up the display, but no power brick. You need to provide your own, or have a faceplate outlet that includes USB connectors. Otherwise, everything runs off of AAA and AA batteries. Read more

This product has an easy to follow instruction book that comes with it. It works great. It’s just what I needed. I like that there are three sensors plus being able to see the temperature in the house gives you four readings at a glance. The price is very reasonable at about $25. It is very accurate. It doesn’t require any Wi-Fi. I like that it uses batteries. Read more

This is a nice unit and does its job well. The only negative is that it only goes down to 14 F which limits its use in cold climates for monitoring outdoors. ( that is why I rated 4) The unit sets up and pairs quickly with minimal user interaction. I am using mine to measure the temperature under my house where my water pipes are to be informed if freezing is a danger. I did have a plastic molding defect on my unit. I emailed support and a replacement came in 3 days. I appreciate that they backed their product. If your application fits the unit temperature range I recommend it. Read more

I’ve been using this indoor/outdoor thermometer for a bit now, and I’m really happy with it. The 4.5-inch display is bright and easy to read, and the adjustable backlight is great when the room is darker. Setting it up was quick — the sensor connected right away, and the range has been solid. I can check the temperature and humidity inside and outside at a glance, which is really helpful for keeping the house comfortable. Overall, it works well, feels accurate, and the design is simple and user-friendly. Definitely a useful little gadget! Read more

This is a good size for a tight space. I keep it on my kitchen counter. Works great and with 3 remotes, I can also see temps all around the house and outside too. I found it easy to set up too. Read more
