Title: good quality, works well
Content: all meters worked well, seems accurate, slight variation in a couple, but very close. For the price, I was not expecting research lab results. I would buy again
Title: Works welk
Content: I used it to regulate humidity while curing my herb.worked well to keep humidity at 72%.simple well lit large read out helps my old eyes adjust Compact and priced right and you get a dozen hygrometers
Title: Great Value
Content: I got these temp/humid meters to monitor the environment of my 3D printing filaments. They're small and fit in the zip-lock baggies I keep the filaments in. Their response is not too precise or accurate (±1°F and ±~3% on the humidity) but good enough for my purpose. Doesn't seem to be a way to switch to centigrade °C or to calibrate offsets. The 2 tiny 1.5V batteries (LR44) are reported to last 6 months and vary in price from $0.59 to $2.00 each. They also come in a case designed with catches(?) or tabs(?) so you can make fancy mounts if you are so inclined. Wholly recommend these where budget is a concern and precision and accuracy is not.
Title: Surprisingly accurate humidity
Content: I was very surprised to find these all provided accurate humidity detection. Using a calibration mix, these all read within a few percent of the target. With other brands, I've found many to be wildly inaccurate. I was happy to see that all of these were accurate.
Title: Cheap but somewhat effective
Content: These are classic Chinese basic quality level. They all came already turned on, and the backs are very flimsy and the retaining tab tends to break if you want to pull the batteries. Also the batteries don’t necessarily activate it when put back without some tweaking. The absolute lowest humidity they will register is 20% even if it’s lower, and even sitting side by side they can register wildly different numbers. Right now I have one at 30% and one at 20% in the same spot. If you want to know that something is sort of dry and something else is sort of wet, these work sort of.
Title: Perfect for my purposes
Content: Bought these as components for filament dry boxes. Good quality and reliable, in the multiple orders I've placed, there's only been one device that arrived with a dead battery.
Title: Do not work - Don't waste your money
Content: I purchased the humidity sensors in a 12-pack quantity to place in dry boxes for my 3D printer filament. Opened the package and all 12 devices read exactly 20% humidity. Left devices out of the package on the counter and they never adjusted, not even by a percentage point. Replaced the batteries, all still read 20%. I checked the humidity in the room with a Zwave multi sensor and humidity was 32%. Placed them in various rooms and they never changed, all stuck at 20%. Put them in dry boxes that were at a verified 8% humidity, still no change. These things just do not work. Just a display without any actual humidity sensing. Do not waste your money on these.
Title: works as advertised
Content: all units arrived working except for 1 that had dead batteries. all temps and humidity levels are either close or exactly the same.
Title: would buy again
Content: these work as advertised... accuracy it within 5 units of humidity... which is more than I'd like, but workable. all arrived with battery tabs intact and all 12 worked. I actually bought 2 sets due to my large harvest. would recommend to anyone storing herbs or cigars.

Title: Great Value
Content: I got these temp/humid meters to monitor the environment of my 3D printing filaments. They're small and fit in the zip-lock baggies I keep the filaments in. Their response is not too precise or accurate (±1°F and ±~3% on the humidity) but good enough for my purpose. Doesn't seem to be a way to switch to centigrade °C or to calibrate offsets. The 2 tiny 1.5V batteries (LR44) are reported to last 6 months and vary in price from $0.59 to $2.00 each. They also come in a case designed with catches(?) or tabs(?) so you can make fancy mounts if you are so inclined. Wholly recommend these where budget is a concern and precision and accuracy is not.
Title: Surprisingly accurate humidity
Content: I was very surprised to find these all provided accurate humidity detection. Using a calibration mix, these all read within a few percent of the target. With other brands, I've found many to be wildly inaccurate. I was happy to see that all of these were accurate.
Title: Cheap but somewhat effective
Content: These are classic Chinese basic quality level. They all came already turned on, and the backs are very flimsy and the retaining tab tends to break if you want to pull the batteries. Also the batteries don’t necessarily activate it when put back without some tweaking. The absolute lowest humidity they will register is 20% even if it’s lower, and even sitting side by side they can register wildly different numbers. Right now I have one at 30% and one at 20% in the same spot. If you want to know that something is sort of dry and something else is sort of wet, these work sort of.
Title: Perfect for my purposes
Content: Bought these as components for filament dry boxes. Good quality and reliable, in the multiple orders I've placed, there's only been one device that arrived with a dead battery.
Title: Do not work - Don't waste your money
Content: I purchased the humidity sensors in a 12-pack quantity to place in dry boxes for my 3D printer filament. Opened the package and all 12 devices read exactly 20% humidity. Left devices out of the package on the counter and they never adjusted, not even by a percentage point. Replaced the batteries, all still read 20%. I checked the humidity in the room with a Zwave multi sensor and humidity was 32%. Placed them in various rooms and they never changed, all stuck at 20%. Put them in dry boxes that were at a verified 8% humidity, still no change. These things just do not work. Just a display without any actual humidity sensing. Do not waste your money on these.
Title: works as advertised
Content: all units arrived working except for 1 that had dead batteries. all temps and humidity levels are either close or exactly the same.
Title: would buy again
Content: these work as advertised... accuracy it within 5 units of humidity... which is more than I'd like, but workable. all arrived with battery tabs intact and all 12 worked. I actually bought 2 sets due to my large harvest. would recommend to anyone storing herbs or cigars.

Title: good quality, works well
Content: all meters worked well, seems accurate, slight variation in a couple, but very close. For the price, I was not expecting research lab results. I would buy again
