Reptile Thermometer 4-Pack Mini Digital Humidity Temperature Meters Gauge Indoor Hygrometer Thermometer AikTryee wiht ℉ for Humidors Greenhouse Garden Cellar Closet Guitar Case

I keep isopods and 2 disabled hamsters. These are very accurate and sensitive, which is just what I needed to keep an eye on temp and humidity. It came with extra batteries and sticky backs. I dont plan to use the stickies and am making a holder for them to make them easily removeable so I can get to the back where the battery is located. The sticky backs seem that they would block battery acesses. The one thats 1% off just changed as I took the picture.I prefer these as both the humidity and temperature are equal in size and make it a lot easier to read. They are small and compact, perfect to not take a lot of wall space in your enclosure. They are quick to adjust. I left them for a day to even out since its very cold where I live. They need time to balance after shipment, thats just how any hygrometer/temperature gage works. Overall I do plan to get more when I need to.

These are great to place around the house to get an idea of how temps and humidity varies by room. Appear to be fairly accurate when compared with more expensive options I own. Would recommend as a cheap solution.Even left one outdoors for a few days but not directly exposed to rain and the sun and it worked fine in a high heat environment. Not sure I would try that in winter though.

They are possibly a degree or so off, but accuracy isn’t my intention, exactly. They are close enough to get the job done! I propagate fruit trees and semi-hard wood cuttings and need to keep my humidity and temp in a specific range. I use 2 of these in my small 10x6’ greenhouse (one at the rear and one near the door) to keep track inside. Also use them inside my propagation boxes of cuttings (as seen in photos) to watch the humidity and temp. These come with command strips to secure to walls and they are very handy! They are a little difficult to read like other reviewers have said, so I need to get directly in-front of the screen to read. But this is by far the best value for multiple pieces! I’m very pleased with my purchase! Also love that it came with extra batteries for when needed!

For the price, these are well made and work extremely well. They are accurate when measuring the temperature as well as the humidity levels. The are about 2 inches in length and they come with multiple sets of batteries which can keep these going for years. I haven't even changed the batteries out yet on any of these and I have had these for well over a year now. I would definitely buy these again if I needed some more but these look like they're brand new still so I don't see that happening anytime soon.

They all register the exact same humidity and temp when placed side by side. So we scattered them around the house and now we can see at a glance the temp in a room. Do not put in fridge though.

Put in an incubator. Works good. Improved hatch rate. Yay.

Very pleased with this purchase. Thermometer is accurate +/- 1° F and hygrometer is consistent among the 4 received.Immediately after unboxing, one had wildy different measurements and I was afraid it was going to be a dud. I put them in the bathroom during a shower and immediately after the shower all 4 were exactly the same- though one changed just before I took the picture as the room temp and humidity began to drop. They each adjust at slightly different speeds, but stabilize within a couple minutes.I compared the temperature readings to those on 2 different digital oven thermometers and my old thermometer/hygrometer (on which the humidity always measures 99%, so cannot compare hygrometers). As long as the temperature was stable, they were all within 2° of each other. My oven thermometers actually measured 1.5° apart. So I'm pretty confident in the performance of these.I purchased these to monitor the environment in my succulent seeding domes, based on the reviews of high accuracy and cost. Monitors with corded probes would have been more convenient, but I couldn't find them at a similar price with good accuracy reviews and without the humidity reading being larger font than temperature. The temp and humidity fonts are the same on these. The humidity reading is first (left), which threw me off initially since I'm mostly interested in temperature, and the temp and humidity readings are very similar in my setting (usually 75-80 for both). I resolved that by putting a small mark underneath the temperature with a silver sharpie, which draws my eye to it.The back portion of these happen to be the exact height as an Avery 5961 address label (1") which I had handy. I cut a label at the measured width and stuck the label onto the plastic humidity dome, cut out the portion with the label, and pressed the back of the monitor into the cutout.I have noticed that the dome-mounted temperature is occasionally a couple degrees below the one that sits inside freely atop the seed trays (there temporarily), but at other times it's spot on. I chalk that up to location and being closer to outside the dome (ambient temp about 15 deg below dome temp). I just set this all up last night. But it's not a big deal if it is a persistent finding.

Can't beat price. Needed it to grow my indoor garden. Works no complaints
