preface
Children's safety has always touched the heart of the whole society. The early film, Dear, was even more tearful and touched the heart. The loss of children has deeply hit every parent's heart. Is there a digital product that can be carried by children to protect their children? Recently, major businesses have also taken a fancy to the business opportunities and launched smart watches suitable for children. Kubi Rubik's Cube has also recently launched a watch with cloud positioning for children's safety protection - Kubi Rubik's Cube Tinker Bell. It's a bit late to understand the brand of Kubi Rubik's Cube. It started from a tablet computer of Kubi Rubik's Cube a few years ago. The initial impression is that the workmanship is average, the price is affordable, and the low-end, civilian line is followed. Relatively speaking, the quality is good, and it can still be used now. Will the recently launched children's watch surprise us? Now follow me to have a look.

Xiaodingdang watch is simple in appearance design. The box structure is opened up and down, while other manufacturers' box design is more fun to find, with more patterns. Individuals prefer this simple structure. This product is available in two colors, sky blue and pink. The one I got is sky blue. There is a big bell on the front, upper and lower sides of the box, which may be a small jingle to symbolize the safety of children. The product name, executive standard, manufacturer, place of origin and some warning information are printed on the bottom of the back.
 
Open the upper box cover and Tinker Bell will appear in front of us. The accessories of this product are relatively simple. The magnetic noodle charging data cable, the manual, and in order to facilitate the installation of the SIM card, a small screwdriver and a screw spare part are specially equipped. Although the power adapter has overflowed, it is necessary to provide Tinker Bell with an adapter, If an inappropriate charger damages the product, it is still difficult to investigate the responsibility, but perhaps more reflects the confidence of Kubi Rubik's Cube in its product quality.

The appearance design of this watch can only be described as satisfactory. The function keys and sim card slots are designed on both sides of the watch. The SOS function keys are used for emergency help, and the other two are used for making and answering calls. In addition, they also provide more functions. The charging port is designed on the back of the watch, so the magnetic suction type not only saves space, but also is more convenient to use. Although the front of the watch is equipped with a diamond tempered glass cover, which is non slip and durable, there is still a gap between the watch and the popular touch screen. The watchbands on both sides are connected by screws, which is easy to remove and replace. The food grade skin friendly silicone watchband, with enlarged holes and grooves, is not uncomfortable to wear even in summer, but its dirt resistance is a big problem, It is better to replace it after wearing it for a period of time.

Xiaodingdang is a smart watch with multiple functions, such as positioning, call function, exercise detection, watch finding, love reminder, etc., but all of these are actually based on the data network. A suitable MICRO-SIM card is necessary. The official said that it can only support Unicom and Mobile. By comparison, here we recommend Unicom with a 4G card of 8 yuan, giving 100M traffic, It works properly. The caller ID must be enabled. The actual meter uses 2G. The card installation is also relatively simple. There are detailed label prompts on the side. Use the screwdriver in the accessory to open the screw, insert the card, and then tighten the screw. When the card is taken out, it is a bit troublesome to find something to push to the end before it pops up. In order to prevent children from taking off the watch, a sensor is integrated at the back of the watch, which can be reminded by setting the mobile phone APP end.

This watch is integrated with a 380mAh lithium polymer battery, which makes the use process safer. For children to use such a watch, it is necessary to charge it every two days, and the power supply is also relatively simple. Through the magnetic suction data line, gently contact the back of the watch to complete the connection. It is a pity that there is no charger. For the safety of the watch, it is best to find a 5V 500mA charging adapter when charging. In addition, this watch does not support the power off function at the watch end, which is very necessary unless the power is exhausted.
 
After understanding the appearance, charging and card installation of the watch, let me take a look at its APP client. This watch has a variety of functions. In addition to the basic call function, it also provides positioning, micro chat, footprints, fences, health monitoring, sos distress and other functions. Complete the installation by downloading the client, register and scan the barcode on the back to complete the binding of the watch.
  After opening, we enter the main interface. We first make simple settings. The sos/kinship number is a must, and three numbers can be set. When a child is in danger, press the sos key, and the watch dials the number in turn. Contact the parents at the first time to deal with it. Don't disturb mode should also be set. It's embarrassing for children to be reminded of sudden information in class. You can set silence period here. Phone book settings, how to make a phone call at the watch end, you must select through the phone book, and add the phone numbers of home and friends to facilitate contact. Only 10 records are provided here, which is enough for children.
The overall design of the APP interface is simple, clear, and refreshing. It mainly provides the following functions, the grid function, which is the so-called ancient circle. When children leave this area after setting, there will be a message reminder on the mobile phone. Footprint function, where children have been, can be mastered at any time, and this function also provides playback. Positioning function: the watch can be positioned by gps, base station and wifi, and the location of children and parents can be known at any time. How the children behave can be praised by star grading.
The SMS function is quite good. You can send SMS to the watch through the app client. This function is still useful. The alarm function is also very necessary for children.
Let's focus on the voice intercom function, which is equivalent to QQ voice. After the client records, it sends out the voice, and there is a prompt on the watch end. Short press the sos key to play. Long press the phone power button to record, and release it and send it directly to the phone client to facilitate communication between children and parents.
Conclusion: This watch is simple in design, convenient in operation, and versatile in function. A good children's watch provides a safety protection barrier for children and parents. For the safety of children, it does not reproduce the film's dear sad scenes. Tinker Bell, with reasonable price, is worth owning.
