Good at first glance
Got them today. They were actually all nearly identical in RH and Temp right out of the boxes. Setting out on the table for a few hours they are all the same RH now and within 1 degree F of each other. They are powered up already.The change from C to F is kinda a kluge. You need to use a metal object to short the circuit you can sort of see through the hole on the back, then once it changes quickly pull the metal object out and hope the F stays. It took a couple tries on some but it is doable.For the price they are absolutely worth the money so far. If they start to die I will post back, but I suspect they will last long enough for my purposes.I bought these round ones instead of the rectangular ones because it will be much easier to mount them using a simple hole saw.

5 units. 5 different readings. Need to acclimate.
Disappointed. 5 units, 5 different readings. No instructions. Can't figure out how to change from F to C. I was hoping to check temperatures in 5 different rooms, but not one of theses reads the same. They all give different readings by more than a degree C and one has a 20% higher humidity reading than the rest. But, for the price, not worth sending back. Kinda bummed.**edited**After a day of acclimation, they all read within a degree and a couple % humidity of each other now. Also, to change from C to F, you need to insert a conductive rod (big copper wire, etc.) into the hole in the back to activate the conductive webbing on the circuit board. I think the button is missing that's supposed to do this.

Don't buy junk from China......Buy American!!!
amazon no sooner dropped this on my porch and I had these five little boxes opened and setting on my counter... as you can see every one of them are showing a different humidity READING after 10 minutes adjusting to the room the one on the end is just flickering .... SURE GLAD I THOUGHT TO TEST THEM BEFORE TRUSTING THEM .. BEWARE....... CONTINUED starting here.. the first part of this review was done a week ago when these arrived and I realized they were junk.. . from here to the end will be for what happened after I requested a refund and gave bad review. ok so I don't really know what happened here, But I know for certain that I was very clear and to the point when I requested a refund. But to my surprise ,a request was made from a ghost I'm guessing to have a replacement item sent instead of a full refund like I had asked... so anyways I decided to skip the hassle of trying to reach someone at amazon to explain my situation and see if the replacement item was correct and working properly.. Well just like the first box of five , They all read different numbers while sitting in the same place for hours.. I'm really confused as to why this item I requested a refund on is being shoved at me in this way... I do not want this junk! I was very clear in my first review... Anyone who can read thru my angry full of typos book here... Please steer clear of this item.... 10 different Humidity and temperature readers( two totally different orders) All Junk. you get a better item from a .25 cent gumball machine....This is a true story

Temp Readings for Inside My Car
Many cars will tell you what the temperature is outside of the car. But I have not owned a car that tells you the temperature inside the car. I am in Michigan and would like to know why I feel so cold [or hot].This is not the best gauge to use. It displays the temperature small and the humidity very large.Mounting is easy. PVC tube slice. Shave ID to fit Gage. Add hook and hang off the mirror. Easy.The 4-star is because the first unit did not display the correct readings. The 2nd unit has been working perfectly. Hey, you get four spares...

Accurate And durable set
I keep these in different areas all around mygrow room and they work really great. When I first got them I tested them all together and only two had differences of only one or two degrees; nothing I am too worried about. Wasn’t as easy to press the ‘button’ to change Celsius to Fahrenheit as I had initially had hoped. I have to use a small metal tool to change them but rarely ever have to reset them.

Well it works but...
I have ordered this type of thermostat before for my animal cages. The price is right, so I can not complain about that. The ones I had before had a self adhesive back while these do not plus I can not get these to change from Centigrade. Final problem is that the battery is already installed in the unit, so who know how long they have been that way.

Consistently incorrect.
I was wanting one of these to use with my 3d printer filament. I would say the humidity function is more of a suggestion. The ingest disappointment was these don’t seem to be able to register anything below 18%. A higher quality hygrometer was reading 8% while this read 18%. These will sit at 18% until the other hygrometer climbs past 18%. The upside(?) was that they all seem to read the same wrong information so at least they were consistent.

It works
Battery holder on one seems to be lose. It keeps going out. Other than that, they're within a degree difference.

All batteries were on in boxes - no isolator tab to avoid drain
all 5 were on in the boxes, and the screens were already getting weak. battery voltage on them all was low, and 3 stopped working within the first day. i put a single replacement battery i had in 1 and it brightened the screen right up, so for sure there was under 25% battery left in them all. disappointment ensued.

not really working
Out of 10 (2 packs of 5) I have 7 that actually work.1 is stuck on 14.7C and 29% while it's actually 21.9C and 99% in there.1 display died just completely1 display is barely readable as the text fades away...Not happy. However the dimensions are handy for what I need it for

No way to change temp from °C to °F as described by seller.
Product not as described. I bought 5, layed them all out on a table and after 30 min none had the same readings, though not far off from each other. My biggest issue is they claim that you can change from °C to °F by inserting a pin into the hole marked C/F on the back. Well none of mine had said button within the unit. I’ve contacted seller and they only replied with the same instructions I already knew and would not reply to messages when I stated otherwise. Due to lack of correspondence with seller, I do not suggest purchasing from them. If you are fine with temp in °C, this may work for you. Also of note, all batteries where shipped inside unit without a battery protection tab, so I don’t foresee them working long.

Not 100% accurate
The set is good they are only off by 1-2% and .1-.4 degrees Celsius but compared to my more expensive hygrometer they are reading 2-5% and 1.5-3 degrees Celsius lower. Working great otherwise

If you need accuracy look elsewhere, bargain if you keep them all in one place + average them.
The price is right but the difference in humidity and temperature, between each monitor, is too great. And they often fail and the batteries must be removed to reset them. Return was speedier than most I’ve dealt with.
