Nice large numbers and large display, high contrast LCD. Pretty long battery life, even with rechargables. The sensor batteries especially last a long time (I use lithium so I don't need to change them much, lasts well longer than a year). Nice to see the humidity levels inside and outdoors. Up to three channels for multiple sensors. It can progress through each sensor, showing the value, then moving to the next. Or you can set each one to show just a single sensor, and flip through by touching the screen. Very functional touchscreen. Nice blue light when you want it. Seems like good accuracy. I keep one in the fridge too, and put a sensor down on the bottom shelf in the back. That gives me two temperature measurements so I can keep it good and cold but without freezing stuff in the back. I don't like the white color. It visually dims the display effect. So I put some black gaffer tape along the edges to make it completely black. I think it looks much better this way, and also gives it a nice grip texture. I think they should make them flat black not white. Great product, have had a few for several years, no failures. It's the only kind I use now. Review: UPDATE...Been 3 1/2 YEARS now... - UPDATE...I came to order another Vivosun thermometer (this time with multiple sensors) and thought I'd update the review. Everything from the original review still applies and after 3.5 years and the product is still recommended... - It is more accurate than its specs state. For the unit I received, the temperature is accurate to within 0.5°F (as measured against a very accurate and calibrated thermometer). The indoor hygrometer syncs very closely with my dehumidifier's humidistat reading as well. - It is higher quality than another similar brand (which quit after only a few months). This Vivosun is still working perfectly. - It is expandable (up to 3 sensors). If you don't want to have 3 screens to read 3 areas, that's OK. Just buy another sensor or two and add them to your current unit. Set up is quick & easy. - No need to install any app. This uses local wireless RF (not 802.11 networking) -ONLY bone of contention I have is that the screen-unit needs larger (or more) batteries. It takes 2 AAA (same as the sensors) but with an always-on, sometimes-lighted screen, it really needs either 4 AAA or 2 AA so they don't need to be replaced so often (about every 3 months) (the sensors are fine with 2 AAA) Extra Note: - If you have multiple sensors, you can set the display to show 1 sensor all the time (and then manually tap to see the others) OR you can set the display to cycle continuously through all the sensors at 5 second intervals. This is not listed in the instructions, but is a welcome feature. ORIGINAL REVIEW from 3 1/2 years ago: Been a couple of months now... Wanted to see how it was before writing a review. In short, it's pretty good. I can't really find anything that should knock off a star. The display is large enough to read from about 10 feet (3 meters). A lower-left screen-tap turns on the back-light for a few seconds. The outdoor sensor reads accurately and the humidity sensor seems to work well enough too. No wires is nice, and so far, the battery does not show any signs of wearing down yet. So overall, I'd recommend it and so far, I'd buy it again. ## Features - Precise Data: Vivosun wireless indoor outdoor thermometer records accurate all time/24 hours max and min temperature and humidity readings; Temperature trend arrows indicate whether it’s getting warmer or colder near the remote temperature monitor; Temp Accuracy: ± 1.5°F/± 1°C; Humidity Accuracy: ±5% - Wide Temp and Humid Range: Inside outside thermometer hygrometer measures indoor outdoor temperature and humidity percentages simultaneously: The outdoor/indoor thermometer range: indoor: -4℉-158℉ (-20℃-70℃), outdoor: -40℉-158℉ (-40℃-70℃); Humidity range: 20%-95% - Hands Free Monitoring: Connect up to 3 strong signal penetration humidity sensors to get the temperature and humidity records from 200ft/60m remote range away (enhanced Wireless Frequency: 433 MHz); Tabletop or wall-mountable design; Powered by 4 x AAA battery (included) - Backlight & LCD Touchscreen: Large LCD display features a blue backlight and touchscreen, ensuring the display is easy to read even in dim light conditions; Backlight can be turned on/off, so it’s easy to use whether in the bright sun or pitch black; 12 seconds auto-off - Multiple Applications: Vivosun thermostat can be connected up to 3 wireless sensors (please be advised the package come with 1 sensor), features tabletop, wall, hanging and magnet mounts, so it’s easy to put in any room; You can have it in your baby room, cellar, basement, garden, nursery, grow tent or office ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Z6F5S2M | | Battery Description | Alkaline | | Best Sellers Rank | #97,907 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #41 in Weather Hygrometers | | Brand Name | VIVOSUN | | Customer Reviews | 4.2 4.2 out of 5 stars (6,417) | | Item Dimensions W x H | 4.5"W x 3.8"H | | Item Weight | 0.25 Kilograms | | Manufacturer | VIVOSUN | | Mounting Type | Tabletop, Wall Mount | | Operating Humidity | 20%-95% | | Temperature Accuracy | ± 1.5°F/± 1°C | | UPC | 615435164953 | | Upper Temperature Range | 158 Degrees Fahrenheit | | Voltage | 6 Volts | ## Product Details - **Battery Description:** Alkaline - **Brand:** VIVOSUN - **Item Weight:** 0.25 Kilograms - **Mounting Type:** Tabletop, Wall Mount - **Product Dimensions:** 4.5"W x 3.8"H ## Images ![VIVOSUN Indoor Outdoor Thermometer Wireless Digital Hygrometer Temperature and Humidity Monitor with Touchscreen LCD Backlight, 200ft/60m Range, Battery Included - Image 1](https://m.media-amazon.com/images/I/61X7dXp0C9L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My favorite thermometer *by B***0 on June 3, 2024* Have bought a few of these because they are my favorite among the ones I've tried.

I think I just got a dud! I’ll order again, as I did like it before it stopped working, and the other reviews were so good. The light stopped working after about a month, and now, 3 months later, the outside sensor has stopped transmitting, and the main unit won't change to farenheit.
