Does actually work. Boveda tested it and it s dead on. Also dead on with other calibrated hygros, with no adjusting necessary. Really does work out of the box.
Have been using this unit for over a year and never fails me.
I can't believe this is more reliable than the many digital ones I've gone through over the years. Worth many times the price to me.Comes with a thin profile magnet mounting system. Adhesive has stuck perfectly.All in all, I cannot think of any reasonable way to improve this product. As I said, worth the money and more!
I bought several hygrometers at the same time and out of all of them this little guy is the one that went into my new humidor. Better than the two large analogs I bought here. Easily calibrated,(I placed it next to my digital house hygrometer/thermometer which was verified as acurate), within a couple of days. I like it so much, I'm buying another for my fourth humidor.
Works well after calibrating, easy to read with the nice blue marks & the black trim and bubbled display glass (really plastic ) looks good... hope it holds up.
Works well. The boveda pack I used in it was off by 1.
I was looking for an inexpensive hygrometer to put in a small makeshift humidor I put together at work to hold my ride home cigars in. When I installed this one in the humidor, it was reading 40%. After a humidifier with some Monster venom solution added, It jumped right to a nice 70%. ow I did not calibrate the hygrometer, but I m OK if its off several points because I just wanted something to keep me informed my cigars were staying in the ballpark the short time they re stored there.
So far so good, no salt test needed, works right out of the box, I may test it later if i find its inconsistent, but for right now I like it and the price is right, I ll be picking up more of these little gems for my cigar bags and smaller humidors.
I just bought a couple of these as kind of a back up to my digital ones. I'm amazed that they were actually accurate right out of the box. I put them in a bag with one of my trusted digital units and gave them the old salt test. They were spot on 75% RH just like the digital. I didn't have to adjust them at all.
Opened the box and was on zero. Stayed there all day. Tap the side and the needle just bounces around.
