DIGIFLEX Digital LCD Temperature and Humidity Meter Clock Alarm

This is an excellent device - digital temperature and humidity data, on my desk. Clearly visible. The screen is bigger than I expected. And at an excellent price! And it also does for a desktop clock (with alarm)! I am having problems in a new office we have just been moved to - just too cold - and we are being told that there is no problem. This purchase is providing the evidence for me to argue the case. I have cross-checked the temperature reading with two other thermometers I trust. It is accurate. great product. The only quibble I could have is with the somewhat unintelligible set of instructions. But a bit of trial and error and it was easy to set up. great bargain! (and the delivery could not have been quicker!)

Let's deal with the positives first. The product looks just like the picture and the display is easy to read. But now the negatives. From reading lots of other customer reviews, it would appear that there is no guarantee of accuracy with the temperature reading. The one I bought (and tested against my home brew thermometer) was 1.5°C over. The instructions are a disgrace and let the product down badly. I actually bought this meter for a 77 year old, and he couldn't make head nor tail of them. Now I'm 'usually' pretty good setting up appliances without instructions, but if you're not, then you're in trouble! Here's what you need to do to set up the functions (and note that every key press is confirmed with a loud beep): Clock/12 or 24 hrs/Month and Date sequence 1) Press the MODE button and keep it pressed for 2 secs. It beeps and the hr display flashes. 2) Press the ADJ button and this advances one hour each press, or keep it pressed to move rapidly. 3) Let go the ADJ button when you reach the correct hour. Press MODE again and this time the minute flashes. Press the ADJ button as before and let go when the minute is correct. Press MODE again and choose between 12 or 24 hour display with the ADJ button. Press MODE again and the month flashes. Press ADJ to set this. Press MODE again for the date and adjust with ADJ. After the settings have been completed the device shows the clock as default but you can check the month and date by pressing the ADJ button briefly. After a couple of secs the display automatically returns to clock. Alarm The alarm icon was set on. Press MODE for 2 secs to turn off the alarm and the icon disappears. I can't help with setting the alarm as I couldn't figure out how to switch it on again! My friend didn't want the alarm anyway. Temperature and Humidity The default display shows the current temperature and humidity. To check the Maximum and Minimum Press the MEMORY button once to advance to MAX and once more to MIN and once again to return to default. Each press is confirmed with a beep. Clearing the MAX and MIN memories Press the MEMORY button once to advance the display from default to MAX. It beeps (as above). Press the MEMORY button again and keep it pressed for 2 secs until it beeps to confirm clearance (and reset to current setting). To return to default, press the MEMORY button twice. Press the MEMORY button twice to advance the display from default (via MAX) to MIN. Press the MEMORY button again and keep it pressed for 2 secs until it beeps. To return to default, press the MEMORY button once. Toggling the temperature between °C and °F On the back of the product lift up the display stand. There is a small black button behind there with a sticker. Each press toggles between °C and °F.

I purchased two of these units and both are very clear and clean displays. It is very easy to see the temp and the humidity in an instant! There are a few options to change things, such as F or C for instance. The time, though not required, for me is a handy feature but I wish they had that AND the date displaying at the same time. These values alternate around every few seconds, and it almost seems that every time I look at it it's showing the wrong value, so I want to know the time, for instance, and of course it is displaying the date....ugh, so I have to spend a few seconds staring at it like a clown until it swaps over to the other value >) Why on earth they made the button beep so ear piercingly loud is beyond me. Maybe the chief designer was hard of hearing but every button press produces a very annoying tone. Having to set the thing up in the first instance drives me mad, let along another else in the near vicinity! One day I might perform an autopsy and remove the speaker. When you changes batteries the whole system resets to factory defaults, would have been a nice touch to have a battery backup capacitor in there or something, but lets not forget this is built to a cost. Over all between the two I purchased they seem to report more or less the same values, so I am a very happy owner of these devices. Thumbs up. (whilst still holding my ears in case I press one of the buttons!)

Bought this to keep an eye on the temps in my room since it regularly gets very hot. There are however 3 problems I've found with this device. 1: The clcok cannot be trusted. I set the clock, left it overnight, by the next day it was off by 10 minutes. Left even longer, after a week or so it was off by well over an hour. Batteries were brand new etc, so the clock portion is terrible. 2: The alarm, this goes hand in hand with the clock really. So to flesh this out, there's a reset button on the back, this button sets everything back to 0:00 so you need to reset the time again if you press it accidently. 3: I don't trust the temp it gives me. Had the thing on my windowsil for an hour, the coldest part of my room by an open window and it dropped to 21.1C. Moved itto the graphics card exhaust on my PC. Something I know pushes out air at around 30'C hit about 24'C Moved it to a netral position and about an hour later it was on 25.1 I just don't really trust its accuracy at all, especially with the clock issues.

I've been using it now for about a month and I am completely happy with it. It does it job: shows time, date, temperature and humidity. It is quite sensitive, leaving a cup of tea somewhere close will bring an increase to temperature, which means it's really working. Someone complained about the noise the device is making when pressing buttons. True, it would awake anyone nearby, the thing is though that I used these buttons only once, in the first day when it arrived, to set up the correct time and date. Since I didn't have to touch them even once. I like device which do not have to be taken care of :) So if you are looking for relatively cheap and good quality room thermometer I can recommend.

As this item was so low priced and came all the way from the far east with no delivery charge, I have to be honest and say I wasn't expecting much. It is however a GREAT little item. It does all it says it will in the description. I bought it for a greenhouse with some delicate plants but really it's actually way too good to put out there. I think I'll keep it on my desk instead, especially as the clock alarm function will be great for meetings etc. It's quite stylish looking and has good clear, quite large display, is very accurate and has pull out legs at the back so it can stand upright. The seller emailed frequently to update on progress of the order - fantastic service for such a cheap item. I'm a very happy bunny with this order!

PROS: * Functional, technically in working order. Displays numbers on the screen. CONS: * Shipped with a "Penesamig" branded battery (an obvious Chinese knock-off of the Panasonic brand name). Internet search indicates credible widespread suspicions about the build quality of these batteries. Shipping the device with this suspicious battery will cost me an extra trip to the council's waste disposal unit 1 mile away, as I don't want to risk my house setting on fire because of a badly made battery... I would rather that the device had arrived with NO batteries at all than a badly made one. * Device is obviously very cheaply made. For example, the battery compartment has a poor quality, ill-positioned spring that has to be manually bent into a different shape in order to ensure a good electrical contact with the base of the AAA battery (I haven't seen this style of battery compartment in any other devices for about 15 years). Even the when the compartment spring is bent into shape and forced to fit, the AAA battery is trying very hard to pop off the back of the cheaply made plastic battery compartment cover. * Colour is slightly different from that suggested by the photograph (white and dark-grey plastic; rather than white and black). In certain lighting conditions (especially sunlight), you get very visible rainbow effects on/in the transparent plastic screen; which suggests that the screen cover plastic is very cheap (with variable thickness, finished with cheap chemicals) with an air-gap at the back between the cover plastic and the actual LCD screen. This is NOT a device you would give pride-of-place on your mantelpiece, or display proudly on your office desk: it's a functional device that merely gives a rough idea of temperature and humidity levels. * This seller "forgot" to mention certain specifications on the product packaging, such as: temperature only accurate ±1℃; humidity only accurate ±5%RH. Mine has a systematic error >1℃ below the reading from my other digital thermometer (readings fluctuate wildly over a 1℃, 5%RH range from minute to minute, unlike my other device; but this error-responsiveness does not translate into responsiveness to actual ambient conditions: the device takes several minutes to respond to new conditions after being taken from one room into another). I bought this for humidity readings so I'm not too fussy about the temperature reading; but with only 5%RH accuracy, this device is by no means accurate: you're almost better off using your nose to smell the air humidity levels, and using your hair and feet to gauge whether there's any static electricity in the air/ ambient environment. * As shipped (from Singapore; originally "Made in China"), the official customs declaration on the package suggests this is a "gift". Well, if I paid four pounds for it, then I don't think it's a gift. Is this a tactic to avoid paying customs or sales tax on the cross-border shipment? Not sure... * Shipment includes card explicitly asking buyers to give five-star ratings on Amazon (I'm not impressed with this "request"...) OVERALL: For just 4 GBP, I would have given this four stars as "you get what you pay for" (readings with very limited accuracy and no value to scientists or engineers). But given the suspiciously made/branded battery included, the badly made battery compartment, the questionable customs declaration and the explicit "request" for me to give this product a five-star review; I'm giving this three stars.

... that there are two versions of this - one is GOOD but the other is BAD. Both are made in China. I have to mention sellers here because it really seems to depend on which seller you choose whether yours will be good or bad. Note that I have used a standard reliable liquid thermometer to gauge accuracy. The two GOOD ones that I bought were from 7dayshop and are accurate within 0.5 degrees centigrade. They keep good time and their MAX/MIN 'memory clear function' works. I cannot confirm or otherwise whether the displayed humidity is accurate but it does increase in and near the kitchen during and after cooking a meal - as expected. The instructions are in English - admittedly something is lost in translation but they are reasonably easy to follow. I chose 7dayshop as I have bought other stuff from them previously with no problems. I was so pleased with the two that I bought from them that I decided to buy more. Unfortunately they had sold out and I had to find a different seller. I chose another UK-based seller: Dallan Trading Company. Of the two I bought from them, one is BAD and I haven't opened the other one (although the seller wants me to do so before they will consider replacements). Temperature is consistently displayed as 4 degrees centigrade higher than reality. The MAX/MIN clear function doesn't clear memory and the button is unstable and sinks in. It is also different to the good ones in that the IN/OUT indicator does not show on the display and the date does not alternate with the time. The instructions (and printing on the battery) are in Chinese so impossible for me to read - fortunately I could use those from my first purchase. I know they cost very little but when you add up the thousands of customers buying these that's a lot of dosh!
