Bought 2 of these the other day. Opened them up, put in the battery, and they were ready to go. I bought two of them so I could install them in each of my childrens bedrooms so I could tell the range of the temp and humidity each of thier rooms. First I put these next to my house thermostat which has a current temp and humidity displayed. After 1 hour of being in the same room right next to the thermostat both of the Cheney units read exactly what the temp was, and the humidity on both units were the reading the exact same (7 units higher) then my house thermostat. I don't know if my house unit is accurate or not but at least the two Cheney units read the same for temp & humidity. If they read differently than each other than I would say they weren't accurate but since both read the exact same things I give them two thumbs up and agree this is a great buy, especially since it displays the current temp and humidity and displays the daily low/high for each. Great Product!!!! Small, lightweight, has magnet on back to stick to fridge or can use clip to attach it to belt, or anything it can clip to. It also can be placed on a desk, shelf, etc but standing it on end with the attached stilt.

1.0 out of 5 stars design flaw January 7, 2012
By Stimpy
Amazon Verified Purchase
Well like everyone else says, this product is ok for temperature but leaves a lot to be desired for reading humidity. This being said, with a few mods it works fine as a hygrometer. I added a few more holes with a drill approx 1/8" and now it actually reads humidity quite well. I added a total of 13 holes around the unit, 5 on each side and 3 on the bottom. Now it adjusts the humidity reading every 15-20 seconds and levels out in about 10 minutes and actually reads the right humidity when compared to my dial hygrometer. So this tells me that there is a design flaw with the amount of air flow allowed by the factory vents, thus not allowing the unit to process the volume of air needed to make accurate readings.

ok had it a week and like another reviewer stated the LCD readout has gone blank in a few spots. not dim just not there anymore. Its junk. Off to buy another Hygrometer from someone else.

4.0 out of 5 stars Great inexpensive digital hygrometer December 21, 2009
By Timm
I bought this same hygrometer packaged as Acu-Rite brand from a Mill's Fleet Farm for $9.99 more than a year ago. I've always had it turned on since then, and I've never had to change the batteries. I tested the unit not long after I bought it and again just yesterday (using the NaCl and distilled water test and the Boveda humidipak kit) and after 8 hours the display stabilized at 75% just as it should. I also made a Potassium Carbonate test and it was stable at 43% after ~18hrs. This is great to see from a $10 unit. I've traveled with this product and it has held up through that as well. I've never tested the accuracy of the thermometer, as I mainly bought this instrument to read RH in an instrument (guitar) room, and guitar cases. I've also owned "The Weather Channel" brand weather stations with built in hygrometers that were more than twice the cost of this product, and found them to read more than 10% off when testing.
Maybe I got lucky and happened to buy a accurate unit, but from my experience with this I highly recommend buying yourself one.

PS I have since had relatives buy these units and they were not as accurate as the one I bought, so I guess I really might have just been lucky. The other units seemed to report higher humidity then existed (when RH was 40%, they showed +3-5%, which is considerable). The plus side is that they don't seem to get worse over time, so if you know the unit to be off by a certain amount, you should be able to predict the actual RH.

1.0 out of 5 stars inaccurate and disappointed
Products were so far from accurate; it was very disappointing. Could we have received a dud?
Our home air conditioner system was on 69 degrees; this product read 83.
