Perfect multifunction digital clock!
Very nice little clock that is powered by 3 triple A batteries or powered by the provided cable which can be connected to a USB port. Whilst the screen isn't exactly how it looks on the image, it still displays all the same information just in different areas. It's live indoor humidity gauge is very handy for seeing how humid your rooms are and with how portable the unit is you can quickly and easily check different rooms within minutes, and it's live thermometer is very handy and quite accurate when comparing it to a traditional thermometer. It has 3 brightness settings that you can choose as well as a backlight button on the back which, when powered by batteries turns the backlight off and on again at the setting you had it on previously. It's alarm clock function is rather good, a little quiet but if you're placing it on a bedside table you shouldn't have many issues, it starts off with one beep every second and gradually gets more and more annoying so definitely works getting you up on a morning. I would definitely recommend this to anyone as it's perfectly good value for money and works very well.

Everything you would want it to do
So it arrived today, and have to say I'm quite impressed... Opening the box was a bit plain and didnt have much on it apart from 5 features, but its going in the bin so doesnt bother me much USB provided is long enough for usage Setup was easy and took very little time to have the time and date set Thermometer and humidity sensor are really good (aulthough it was slightly higher than my phone but it has a min and max toggle so that might have been why) Theres also a temperature trend for the last 24 hours which seemed pretty cool too, but I wouldve preferred it to be static as it constantly lights up and gets annoying after a bit. Display is punchy and can be dimmed to not ruin your eyes - wouldve loved it to be OLED so the colours are more vibrant but at this price, I can't complain... Only bad thing that stops it from getting 5 stars is that I can't tell the weather (it is advertised though so cant say it was a surprise) Alarm Is loud and adequate enough but i prefer to use my phone, as it tells me the daily weather and my schedule (something If this had, I would use in a heartbeat) Other than that, for the price point it's really a good buy Oh, and customer service is A* (use this same company to buy my screen protectors and have had no complaints). Just thought I'd mention it too seeing as they do include a card to say if theres anything wrong you can contact them

It's cheap for a reason
For the price this is good however I would not reccomend it if you are wanting to view it constantly. Reason being is that this does not have the best viewing angles. I wish the back light functionality would stay on with batteries (but I assume it would die quickly). The clouds and sun are a bit of a waste of space on the screen, but I knew that before buying so I was okay with it. There are good functions with this however its a bit small and cramped with all the things it displayes. The temp and humidity info is useful though! Main reason for my purchase!

Easy to use
1. Sensitivity of temperature and humidity - This is good and accurate. It matches with the temperature on my phone and the news etc so this is accurate. 2, Whether the time setting and date setting is easy? - Yes i find this easy enough, the instructions are clear on how to do this so no problem here. 3. Is the alarm loud - Yes this is loud enough and works well as supposed to. 4. does the snooze work well - yes this is working fine, no issues with this! 5.Does the backlight function work well? - This is good when using usb however it stays on for a short time on battery. Imagine if you were taking this with you on vacation then it wont be easy to use usb so battery would be best in this case so extending the backlight would be helpful.

you can not read temp or time if it is not plug as the screen is to dark
it works well if you could read the temp and time on as the screen is so dark you cant read it you need to have plug in all the time to keep back light on cable that comes with it is so shot and no plug it makes the item pointless and use less.

Good multifunctional clock/temperature/humidity device
I bought this device on recommendation and I am not disappointed. It is well-made. This device was easy to set up. You can change the temperature from F to C easily. It has a power outlet as well as batteries, so I no longer fear power outages resetting my bedside clock. Everything is on one, easy to read screen, giving you all the information without fiddling through menus.

A decent device for the price
Does what it says on the tin, really. Tells you the temperature, humidity, date, day etc. The temperature seems to be fairly accurate when compared to our central heating thermostat, just as long as you don't leave the device in direct sunlight. We have no idea how accurate the humidity measurement is, as we have nothing to compare it against. The 'temperature trend' function is interesting, but I don't know why it's constantly animated. This seems unnecessary. The alarm function is quite nice. The alarm tone grows in intensity the longer you leave it. Setting up the device with the correct date and time was fairly easy. It doesn't have a memory, so you'll have to do this every time you unplug it or change the batteries, but it doesn't take too long. The icons in the top left change based on temperature and humidity (I think...). Sometimes it shows clouds alongside the sun, and sometimes it shows a little smiley face. There isn't a key, so I'm not sure what it means. The 'sound control' function is great. Being able to clap from across the room and see the device light up is good fun, and useful too. Overall the build quality is okay for something so cheap. The screen is fairly legible under most lighting conditions.

Compact Digital Clock with Clear Display
Really good compact digital clock. Very clear, colourful display. Time, temperature and humidity readings. Easy to operate. Can run off 3 AAA batteries or using the USB cable which is supplied. Well recommended.

température incorrect
Bonjour, Il n'affiche pas la température exacte, il y'a au moins 2°C de plus que la température de la pièce.
