Bought 2 sets. One for me and one as a gift. Has been over a year and haven't had to replace batteries and they've been accurate the entire time. Amazing for the price

Temperature seems somewhat accurate.Humidity not sure of. Inexpensive for two pack and consider them a disposable item if they fail or get lost. Recommend a bright color device so they are more visible and perhaps less likely to get lost or misplaced.

My eyes aren't what they used to be & I guess I've gotten a little lazy - why do I say this, well I find reading a mercury temperature gauge difficult now when I just glance at it - I have to get up close & sometime I'm just too lazy to walk over to it to do that. I can just glance at these & see the current temperature from across the room if device is angled right & lite right. Additional bonus, you also get a humidity reading with this device also. When it comes to accuracy of either reading - just look at clock devices, you will see that they may be a little off from each other, by a second or two but they eventually show the same time - that's how I judge these devices, they may not be right on but they are in the same ballpark with what the temp/humidity is at. Battery life, I forgot these require a battery. I've had these since 01/2024 & they are still functioning and it is 05/2024 at this writing. You can choose either C or F. I like the variety of colors the device comes in, got favorite color which is purple. There is a magnet on back for stick on application. It also has a flip out stand on back for tabletop display. Finally, you get 2 of them.

I have several all over our hold house. All thermostats can be +/- 2 apart, but isn't over that when pre-test side-by-side. I'm reassured can check temp/hum quickly and they don't take up much space.

I think they show the right temp.
