Digital LCD Temperature and Humidity Meter Clock Alarm

This product is excellent for the price point. I did a comparison with some calibrated instruments and it was near dead-on accurate for all intents and purposes (temperature within 0.2C, humidity within 3% checked at about 22C and 45% humidity). The only thing I could not test was the accuracy of the clock but it appears to keep good time.

If you can set a digital watch, you don't require instructions for this, I had it up and running within minutes of receiving it.
Pros;
« I have a weather station and the readings are about the same.
« Set up in no time at all
« Fast delivery. Wow
« C% and F% for those who want it in real money ;)
« Robust and display reasonably well laid out
« Only had it for a few hours so will update if I hit snags

Cons;
« Forget the alarm and hourly chime, you would have to be a bat to hear it, who needs it though?

I bought this to make sure I wasn't using my dehumidifier to the extreme, as it checks out with the weather station I am more than happy to recommend it.
4 stars, give it 5 and it will go up in price.
Oh, I have just noticed the photo, it must have been taken in a sauna. 45 to 55% is the ideal range. My dehumidifier is factory set to switch off between 50 & 55% (Ebac uk)

UPDATE

I bought another one of these as my mum had acquired the first one; well actually we gave it to her expecting to reorder when we got home. The price had shot up but now it is, at the time of righting, back to a sensible price I bought it, now the crunch.
The design has changed; reset and F to C are under the stand, not very convenient.
The time/date display toggles every 5 seconds (most irritating).
Certainly the sound is way louder on this one but I don't use it, just thought I would keep you informed.

This seemed the best choice for the functions I needed, without paying for too many functions I wouldn't use.
The unit is big but somehow manages to be unobtrusive: The contrast on the display is enough so I can read the display from across the room, but low enough to not be in your face. It blends in well, and I find the layout and design of it very pleasant.

The instructions are basic but time and date are very easy to set. Hold "mode" button for 2sec, and the first adjustable value starts flashing ("24hr" in my case). Press "Adj" button to change the value (for example "24hr" to "12hr" clock mode, or press repeatedly when setting time or date to make the numbers go up). When you've set the value you want, press "mode" to go to the next value.

There's one thing I really don't like: It makes an ear-piercing beep sound every time you press a button. It's about as loud as the battery warning beep on my smoke alarm, and as far as I know it can't be switched off. (That kind of customizability would be too much to ask at the price, but I wish I'd known.)
So no chance of checking min/max temp or setting the alarm or anything like that without making half the house jump/wake up. I'm contemplating trying to disable (well, destroy) the beeper element, since I can do without the alarm function.
If you, however, have impaired hearing or difficulty waking up this could be a big plus. I have a disabled partner who has sound hypersensitivity, so for us it's a minus.

The other thing is quality control. The plastic and screen of the unit look great, sturdy, not cheap looking at all. Proper ABS plastic. BUT they seem to have been assembled in a rather dusty place. The unit was blister packed, so it's not to do with dusty storage, it's inside the pack and, sadly, even inside the unit. There is dust and some grime in all the seams and annoyingly there are a couple of small white plastic flakes stuck behind the screen cover, right in the middle of the display. I'm sure I'd get a replacement if I asked, but I'd feel that weighing on my eco karma. The thing does it's job! So I'll clean the outside and accept the flakes as an element of character. ;)

So, good job unknown chinese company, but sort out that dust, can't be good for your employees either.
