Vaikby 12-Pack Mini Digital Thermometer Hygrometer, Indoor Humidity Monitor, Temperature Humidity Gauge Meter with Fahrenheit (℉) for Humidors, Greenhouse, Garden, Cellar, Closet, Fridge

These are great. Have been super accurate. All worked. Nice value for money. Portable. Readable. Great battery.

I am a big gardener and houseplant enthusiast and have multiple areas to monitor my plants in, which is why I ordered this 12 pack of thermometer/hygrometer combos. I have propagation greenhouses as well as areas with grow lights that can get warm, so being able to put a small thermometer in each location is super helpful. I also have many tropical plants that do well with more humidity, so being able to check those areas is also a huge help. Also this multi pack makes it easy to share the extras with friends, which is always nice. At the current price of about $16 for 12 of these, it seems like a pretty good deal, as long as they stand the test of time (if they don't, I'll try to remember to update my review). So far so good, and they've been helpful and worked well for me, so I do recommend them to others.
