AyayaBoss 3-Pack Room Thermometer Indoor Hygrometer for Home, Digital Sensor Mini Humidity Meter, Temperature Humidity Gauge Monitor for Bedroom, Pet, Plant - Battery Included

neat size ,work well , and good value .Temp and humidity readings were all accurate on all 3 readers

Perfect. On my second pack of these (need more of them) Really simple batteries tend to last over 1 year. Did have one that didn't read humidity correct but otherwise all good. Didn't stop me from buying again!

Good price for three does the job for 3 rooms and are mobile makes life easier

These seem to be accurate (with each other and with the dehumidifier I have). Useful for keeping an eye on the humidity throughout the house and the temperature of the upstairs when the heating controls are downstairs.

Small and neat.Clear display. Great value.

Good but small

After looking at the other reviews I was a little put off by some, but went ahead anyway. My three units were simple to set up, calibrate and give very similar readings. Humidity in the room initially was stable at 47% or 48% across all three units. After turning on a humidifier they tracked each other up to 59%, never disagreeing by more than 1% at any time. I don't know how the number would compare with an expensive piece of kit, but I was after a clue as to how wet or dry the air was, and these seem to track changes in a useful way. Temperature across the three units never differ by more than 0.9C, and each tracked the change when the central heating came on, staying in close agreement. So, for very cheap units, they seem quite good so far. And for those complaining that they can't read them in the dark there is a simple solution - turn on a light!

Good for keeping an eye on the humidity and temperature for my plants

Great value for a 3 pack! Comes with batteries and easy to switch between F or C. Consistent between all three units agreeing on temp and humidity.

Very handy and accurate. I use these to balance temperature in our home. We have a central system and a split heat pump. These devices help me balance both heats and AC. They are very small and have a little stand that folds out so you can leave one where you normally sit, next to your bed and maybe the kitchen. They take an hour to get accurate but once they do, they work fine. The price is great. They work great, and you get 3 for the normal price of one!

These are great little Hygrometer's. Perfect for my project. I am creating terraiums from different types of glass vessels. These are the perfect size for my project and work very effeciently.

Super product, good price they all work fine

Petit et parfait fonctionne bien
