7 Color LED Alarm Clock Review (with calendar, temperature and more)

Presentation of the 7 Color LED Alarm Clock

In this review, we would like to present this 7 color LED alarm clock that we received from Chinabuye (SKU:30081). It is a simple digital clock that has 7 color lights (check the video below) and has some other functions besides clock. The package also includes an user manual, where there are all the instructions to configure and use this device (model HSD110A).

Regarding its quality, it is made of plastic, has a LCD display (vertically) to show its functions and has a base so you can put it, for instance, over a table in your home or office.

Following are the features of this LED alarm clock:

• 7 different colors LED (it is optional turning it on).
• Clock / Time function (12 or 24 hour format selection).
• Alarm Clock function (8 alarm musics).
• Temperature function (Celsius or Fahrenheit selection). (*)
• Calendar function (day, month and day of the week from 2000 to 2099).
• Countdown Timer function (maximum: 180 minutes and 59 seconds - 3:00:59).
• Powered by 3 AAA batteries (not included).
• LED life about 100000 hours (or 11 years).

To switch among these functions, press the "M" button (underside) or push the screen lightly to back (check the images above or the video below). By the way, at the underside you will encounter 4 buttons to configure the functions, a switch (left) that, when ON, will return the display to clock function after 10 seconds of idle (without pressing any key) on any other function and a switch related to the colored back lights. That last one (back light) has 3 states to control:

• OFF: No back light.
• ON: Colored lights all the time (be careful with battery power).
• TR: Colored lights will be on while some operation is being made then will off after 10 seconds of idle.

Now talking about the alarm function, it has a mono speaker at the underside and its sound quality is probably enough if the purpose is just waking you up, unless, of course, if you have a very deep sleep that prevents you from listening the alarm sound.

Since we do not have the knowledge in music, we only recognized two of the eight musics: "Happy Birthday To You" and "William Tell Overture: Finale". However, case you are curious about the alarm musics (do not expect a MP3 quality), and other things, we made the video below showing the main features of this 7 color LED alarm clock.

As showed in the video, the back light colors are very cool, but they are for short time enjoyment, so do not turn it on for long time or else the batteries will run out more quickly.

Where can I buy this 7 Color LED Alarm Clock

This bedside clock (and other locations) is for sale for about $7.8 at Chinabuye (check this link). Good product for gifting someone or to decorate your home/office.

Note 1: According to Chinabuye's description, it can display temperatures between 0º and 50º Celsius with a precision of ±1ºC.

Invisible Ink Pen with UV Light Review

This invisible ink pen (sku.88) is a funny and useful product sold at Dealextreme (and some others stores). With it, you can write hidden messages on a paper and then, when you turn on its UV light and point it to the message, it will be revealed (see the video below).

Besides the invisible ink, it contains an UV led (to reveal the written messages) and 3 (three) AG3 batteries.

Its size and weight are similar to a regular pen, so you can carry it everywhere.

Style

We acquired six invisible ink pens from Dealextreme. The only difference among them was the package (see the images above).

About the colors, it seems that Dealextreme and Focalprice sell only one color (purple). Suntekstore says that it has this item in many different colors (according to the description and images). Tinydeal sells a version of this item in red with some images on the pen, but the essential of all of them are the same (invisible ink pen with an UV light).

Price

The invisible ink pen is very cheap and can be found at Dealextreme, Focalprice, Tinydeal and Suntekstore for about $1.35. Tinydeal also sells an item pack that includes 3 invisible ink pen for about $4.4.

Build Quality

Regarding the build quality, there is not too much to comment. You just need to avoid hit the UV led, because it can stop working.

One day the invisible ink will run out, so you may think to fill it again, but the invisible ink pen is so cheap that it is worth to buy a new one than to refill the current.

Usefulness

As we mentioned, you can use it to write hidden messages on a paper, wood, skin, metal, wall, cloth and some other stuff. That is not so useful, but it can be very funny if you show it to your friends.

Another usefulness is to use the ultraviolet light (UV led) of the invisible ink pen as a counterfeit bill detector. Just turn on the UV led and point it to a bill to see some watermarks present in legitimated bills.

LED Flashlight Keychain 22000 mcd Review – 10 pack

This LED flashlight keychain (sku.1100) is a small item, but it is big deal that you can buy at Dealextreme, Focalprice or Tinydeal. It has a bright light (22000 mcd according to the specifications), is lightweight (about 7 grams each one), is powered by 2 (two) CR2016 batteries and, besides the simple ON/OFF button, it has a switch to keep the light on (powered) without pressing the button (if you prefer). By the way, instead of 1 (one), this item has 10 (ten) LED flashlight keychains.

Style

We ordered this item only at Dealextreme, but we also found it at Focalprice and Tinydeal. According to the specifications, they all sell the same product (10 LED flashlight keychains) and have different color versions (plastic).

The color versions that they sell are:

• Dealextreme: white, black, yellow, pink, purple, blue and green.
• Focalprice: green, pink, purple, yellow, blue and black.
• Tinydeal: green, blue, red, yellow and black.

Price

This pack with 10 LED flashlight keychains costs about $4.5 in each store (each LED keychain will cost just $0.45!!!). Even if 10 (ten) keychains are too many, you can buy and give some to someone else as a gift, because they are too cheap.

Build Quality

The build quality of each flashlight keychain is good, specially the LED, which has a bright light (22000 mcd), but sometimes you may receive a damaged LED that does not turn on (problem in battery or LED). For example, we bought 10 (ten) flashlight keychains, but 1 (one) did not work.

Usefulness

This product is useful at the same situations that regular flashlights are, such as using it at dark environments or using it at blackouts. However, this LED flashlight keychain has the advantage of being small, which allows you to carry it everywhere you go.

If you intend to use it frequently, we recommend that you buy reserve batteries, because eventually the batteries will run out.

Multi-colored LED Ball Review

This multi-colored LED ball (sku.02041) is a great decorative light sold at Dealextreme. The multi-colored LED emits a bright light and keeps switching among 7 (seven) different colors during a few second (see the video below).

It has a ON/OFF switch and it is powered by 3 (three) LR44 batteries (included), but AG13 batteries can be used.

Price

For about $3 (three) you can buy this multi-colored LED ball at Tinydeal or Dealextreme, something relatively cheap considering that you hardly will find it in any store of your city (for now).

Build Quality

The LED ball itself is well made, but its box is a little fragile, like is showed on the above images. But that is not something to worry about.

Usefulness

You can use this multi-colored LED ball as a decorative light of your home or office desk. Or maybe send it as a gift for someone else.

In any case, you should consider the battery life, because they will not last forever. We recommend that you buy a pack containing 50 (fifty) AG13 batteries (for about $4.5) or modify the LED ball to use an external power (USB power, like was suggested for some users of Dealextreme).
