This is a smart bracelet iWown I7, not long listed, the market price of 299 yuan, this product is still on the market when I ask all the gods dig out their minds to get it, had wanted to pretend to experience the mouse, the result Because of the laziness, the products are listed on the market. Here is a quick review of the recent use of this bracelet. We recently paid attention to the exchange of this product.
Simple open box, it is estimated that everyone does not like to see.
Plain, lightweight appearance and detail display
I7's overall design and appearance is very concise and common, and there are no overwhelming advantages in terms of appearance; it should be said that i7's biggest highlight is its all-metal body and the absence of any physical buttons.
This i7 is a new generation of iwown brand products, and its own past products, i7 this design is more popular nowadays square dial, and the use of 3161 full metal body and capacitive touch screen, 2.5D ultra-high tempered glass With the sleek edge of the radian design with the Founder's dial, for the low price, daily exercise of the ribs, this appearance is still reluctant to accept.
With a dial size of 39318.4mm and a weight of only 30kg, the wearing range of the i7 strap is also consistent with the standard wristbands we use for everyday watches: about 16.8-21.8mm.
Just like other brands' smart wristbands , the i7 's watchband also supports interchangeability. The user can change the watchband with different characteristics and colors at any time according to their individual needs. At present iWown is i7 with sky blue, graphite black and apple green colors. Optional.
The use of medical grade TPU material skin-friendly sweat groove with the wristband it relatively excellent wearing comfort, 9 silver buckle and holes to adjust the zoom range, more suitable for all kinds of size of the crowd; the sense to wear in daily life or It's lighter and more comfortable. As for bed rest, it seems to me that it's uncomfortable to have a brand, oh! Â
Magnetic absorption charging is the most popular design of the current smart wristband , so i7 will definitely not lack this function. When the watch back is close to the charger, it can be automatically absorbed in place for charging. The USB interface with superior applicability allows the device to charge Then there is the burden of traveling.
Although i7 can not become a child in life more range of wear jewelry. However, its lightweight, popular square dial and colorful strap, together with related sports monitoring functions, are believed to be a good helper for daily life health movements.
I7 bracelet experience
Fingertip sliding screen and function control
The i7 uses a unique control method of long press and sliding. The specific operation method is: long press to confirm entering the corresponding function, sliding for the function selection; to remind the i7 capacitive touch screen is not as sensitive as we imagine, control failure The rate is higher, perhaps in order to effectively prevent inadvertently designing it, so we need to use certain skills in order to better play the i7's touch function, that is, click and then slowly slide. If you are an "emergent child," I would like to introduce a bracelet and I will suffer!å’»-å’»-å’»-.
Heart rate measurement accuracy of photoelectric Experience
To say that the accuracy of the measurement, Xiao Bian I really did not use a professional measurement equipment to carefully verify, according to official reports, i7 is in the body without any harm to the case of green light, detect the reflection of the green light changes , To illustrate the characteristics of heart rate changes, exercise heart rate can be real-time screen display; allows you to manage their own health more efficiently; but also found in the test process incredible things, this measurement is not only for the skin, like other objects Heart rate can also be measured, such as books or desktops (books still have heart rate? sweating/sweating/sweating). Anyway, it reminds friends, every type of men, you should pay attention to the heart rate record of the evening exercise, otherwise What secrets would she (he) discover? Hey!
Daily waterproof function test
It can be said that the waterproof function is one of the most important video features of our opponent's ring, and the waterproof performance also determines the user's love of the opponent's ring. I thought that the metal body would be difficult to waterproof, but i7 has IP65 waterproof function. The good sealing performance guarantees daily water sports and life waterproof. This is also proved in the actual measurement process. There is no problem in the short-time water bubble.
Data collection and detection experience
Since the i7 uses a dual-core motion processor, the built-in three-axis motion acceleration sensor can achieve more and more important exercise data for runners; it can record different time periods without any manual operation of automatic sleep monitoring function. The sleep state; At the same time, we can also achieve more accurate data collection and detection with the exclusive APP.
Built-in data management and storage
I7 can store 30 days of health data. iwown's secure information cloud service platform can be uploaded and permanently saved through the mobile phone APP. At the same time, it supports 24 kinds of current mainstream sports such as walking, running, tennis, and climbing. Unfortunately, there are still Many features have not been implemented perfectly.
Comes with running assistant function
Bringing a mobile phone while running is really a very ridiculous thing, but the i7 can view the relevant information in the movement process from the mobile phone in real time, such as: heart rate, duration, distance, pace, pace, calories, etc. Synchronize related data with your phone. However, i7 does not have a GPS function, so running without a mobile phone can't show the trajectory.
Music, camera control, device discovery and other interactive features
Information viewing via Bluetooth connection and camera, music, volume control functions are also more practical, i7's touch screen operation can display the latest 8 historical information of the notification software.
With i7 , the phone is in your pocket and you can easily switch songs and adjust the volume! As for the remote control of mobile phones, it is still a very useful function for travel.
Screen display and endurance test
Although the i7 uses a low-power memory display screen, while ensuring reliable clarity, it greatly saves power consumption, but in terms of screen display, the personal experience is not ideal, especially in dark places. The black and white anti-color function in the ring can only be achieved by manual adjustment; I think if you can use light to automatically adjust, wouldn't it be good?
In addition to waterproofing, battery life is also a concern for all of us. i7 's polymer lithium ion batteries have 100mAh of energy, and have a minimum standby time of about 7 days (with automatic heart rate on) and a maximum duration of about 20 days (with automatic heart rate off). In the actual use experience, the automatic heart rate is turned on for more than 4 days. For the battery life, the iwown team also hopes to have a better performance.
Exclusive App Evey Health Assistant Experience
APP voice interaction
Voice interaction is a unique feature of i7's exclusive app. We can quickly query the weather of the day, set alarms and schedules, and consult today's health data through the APP client.
Sustainable Optimization/Updated Evi Health Aid System Experience
Iwown will occasionally optimize and upgrade the opponent's ring system and APP customers' carbonyls, with different styles of personalized dial, the actual experience is also very close to the user's control habits.
The i7 user interface is similar to the old “NOKIA†and does not have a very special and personal place. In terms of dial replacement, we believe that everyone has seen only three, really less, and not open dial design. Let i7 lack of personality advantage over other bracelets.
