Perfect!
After putting this in my humidor, I realized how inacurate the dial gage was. Much better cigars! Couldnt figure out why my cigars were still peeling the wrapper before getting to the end? Not enough moister.

This product worked as advertised. It was a very easy set up & install in my humidor & allowed me to verify my analog gauge was inaccurate & adjust my humidor accordingly.

Zederkoff Square Hygrometer
Very good quality and easy to read. I like the idea of using a regular battery rather than the watch battery that takes days to find and costs a quarter of the price of the hygrometer. I put it next to the Xikar that was already in the humidor and it had a 5% different humidity reading. My old one had been salt tested and was accurate, so I'm not sure why the big difference. Since I can't find a way to calibrate it, I just have to remember it inaccuracy.

Very good product
Excellent product! It works fine, and doesn't look like an overpriced toy. Don't believe the instruction. There is no "tab" to "pull." Unwrap the battery.

Excellent product!
Excellent product! It shows good, clear results in a variety of humidors. I got it at a very good price, too.

Can't go wrong
Gave it 5 stars not because it's spectacular, but because it does what it's supposed to do and does it well. Fast display refresh rate. Move it from box to box and it doesn't take long at all for it to display the different humidity. Uses a good old "gas station" AAA battery too. My other one uses harder to find wafer batteries.

I bought two. They are 10% different. Not as advertised

Good for the price
The calibration was off by 7 percent, and there is no way to adjust. But I can deal with it.

Nice looking but...
The hygrometer is nice looking with a display that is large enough to clearly see. But you can not calibrate it. Compared to my other 2 hygrometers, it is showing 3% higher. If it could be calibrated, I would give it 5 stars.

I Prefer Adjustable Hygrometers
I purchased 2 as gifts. I like that this hygrometer uses a triple A battery. Unfortunately, they aren't as accurate as I had hoped. They're both 6% off my other hygrometers. Not a bad product but I expected a better reading per the product description.

One good, one off
Bought one and it was 75% sharp in salt test. Got another one for my second humidor; this one is about 5% off and no way to adjust. Too bad, it made such a good first impression. What I like is, it's big enough to feature an AAA battery.

75% Out of the Box
Out of the box I performed the salt test and bingo it was at 75%. I like the standard battery over the disk battery too.
2 out of 5
luck of the draw?
Salt tested mine. 10-11% low on humidity measure. No way to adjust. Easy to read and pretty consistent, but nowhere close to accurate. Don't think I'll buy another.

Very Happy with Hygrometer
Checked the calibration when received and was within +/- 1 degree. Is accurate on temperature as well. Extremely happy with purchase

Zederkoffs are a must have.
Finally a trusted, no adjustment needed, hygrometer. My humidity worries are over. Great product!

Perfect so far
I unwrapped the hygrometer, put it in my humidor and it has been working perfectly ever since. I use Boveda humidi-packs and the hygrometer seems to be very accurate, though I have not done a salt test. Now to wait and see how it holds up over time.

Definitely not as good as all of the reviews
I most have bought a bad one but unlike everyone else's response mine did not calibrate to 75% RH. I bought the Boveda hygrometer 75% RH calibration kit. I put my Zederkoff in for 24 hours, 36 hours. I tried this about 5 different times. It never reached exactly 75% RH. It was off by 6%, 5%, 3%, 2% and so on. What a pain in the ass. I understand it never being 100% accurate all of the time but there is no adjustment to make the necessary changes needed. Instead you to remember what degree it is off by and add that to the read out. The one thing I do love about the product is that it takes a AAA battery. Other then that I would completely return it but I do not feel like dealing with the headache of shipping it back and then exchanging it for another or buying a whole separate hygrometer. Save your money and buy a cheaper on that is adjustable.

I think it is too big for my 50 count humidor. Err on short time for soaking it. Mine exploded. Will go w/smaller one next time.

No Hassle
Like the title states, this Hygrometer is no hassle. All you have to do is remove it from the box and place it in your humidor. No adjusting, no testing, etc! Just put it in there and go! Excellent!

Consistent but NOT Accurate
I bought 2. Salt tested them together and got a 69% and a 70% (should be 75%). They are very responsive and seem consistent so I kept them. The idea that they are calibrated and accurate, though, is a joke.

Never worry again.
Looks great, works perfect. I have three Hygrometer's in my humidor, used the zederkoff to calibrate the other two.

No more humidity worries
Got off the make me an offer auction, best deal I've gotten so far. Looks and works perfect. Even came with the AAA battery.

Awesome Product!
No more calibrating dial gauges and hoping you got it exactly right. This gauge shows Humidity & Temperature (F or C) in large, easy to read through humidor glass, digits. Simple to use, install batteries, place in humidor, return 15 - 20 minutes later to read. It's accurate too!

Clean design & display
Product works great. Nice, clean design and good fit. Little pricey but worth it to accent a high quality humidor
Customer Testimonials
Very nice large display. Was dialed in exactly. Best of all it doesn't use button cell batteries.
