Review: Perfect for 3D Printing Filament Storage! - I originally bought these to monitor the humidity in my Bambu AMS units and in my airtight filament storage tubs with desiccant, and they've been fantastic. They're small enough to fit almost anywhere, yet the display is large and easy to read at a glance. The humidity readings have been consistent and make it easy to know when it's time to recharge or replace the desiccant, which helps keep my filament in great condition. They've become an essential part of my 3D printing setup. One unexpected bonus was that each unit came with a spare battery. That was a nice surprise and shows the manufacturer put some thought into the customer experience. If you're into 3D printing or just need a reliable way to monitor temperature and humidity in small spaces, I can definitely recommend these. Great value for the price!
Review: They work great! - Value for price is amazing! I love that you receive 2, which is perfect for my terrarium. I like that you can switch between Fahrenheit and Celsius. I do wish it came with something that allowed you to stick it onto glass easier. Either a suction cup, or double sided tape. These come with an elastic that goes around the meter and you can easily hang it on a hook or something. Let’s see how long they last! So far so good. I’m getting accurate readings and the display is easy to read.

### ⭐⭐⭐⭐⭐ A must-have for wood shops
*by N***Y on September 20, 2026*

It may not be the most expensive/accurate model but it certainly works. It's a low-power (and low-cost) design, so it will not update in real-time. I estimate it checks the reading every 5-10 seconds. So if you just bought it and the two units show different readings, leave them undisturbed for about an hour and check again. I got these because they are panel-mountable. It's about 40mm diameter. I don't have a set of metric hole saws, so I 3D-printed a bracket that I can attach to a bigger hole. The real test for me was when I was applying polyurethane in my basement shop, and the stuff just wasn't drying. I checked this humidistat, which I'd left on a shelf, and it read about 60% RH. Too high for a shop. I kicked on a dehumidifier. The RH went down to about 53% in about 30 minutes and the polyurethane started to cure a lot faster. A really good purchase for DIY projects. If you want something fancier (i.e. backlit display, faster readings, more features) you're gonna pay for it both in power consumption and dollars. For me, this is perfect. Probably going to get a few more to monitor other parts of the house.
