[Xperia Z2 Accessories] shennwuu:
Unfortunately, before buying this band, I had made a lot of research and reading people's reviews on this device but there are just simple touch and go writings which do not really provide a better understanding for people to understand this Smartband and its potential. I do hope I could rejoy whoever using this smart device with its pros and care its cons.

Design

Just like the Fitbit and Jawbone, SWR10 was well-known with its minimalistic yet futuristic looking. Simple structure with high quality strap which is amazingly comfortable to be worn. The textured finishing with a silver colour button made the smartband looks simple and premium. The texture difference between top and bottom of the strap brought a unique outlook when it was came with colours other than black. Featuring a feather-weighted core (main part) did really made users to forget its existence occasionally.

Pros

As rated IP58, the smartband was a water resistant device which brings no fear when you wearing it for bathing and swimming. But NOT FOR SEAWATER! For dust proof aspect, it was not perfect to be burried into fine sand. Checkout the IP rating list for more details.

SWR10 was a life companion as it works perfectly with Lifelog app when both of them not as simple as just a fitness tracking combination, but they do record down your daily activities like the moment when you USING YOUR PHONE for social networking and entertaining. It records the moment when you trigger the camera button and what the photos you take, and even more. Just a double presses on the button at the side of the core, the smartband capture your LifeBookmark and send to the Lifelog to bookmark your interesting moment with location.

The sleep tracking amd Smart Alarm were wonderful for me. Using these features, I felt that now I am able manage my sleep better and wake up fresh every morning. Inspecting the trend of my sleeps, I know my body well and will try out a better relaxation method when preparing to sleep so that I could really rest my body with a longer Deep Sleep phase.

Vibration feature does really helps me a lot at pushing notification from phone to my smartband and also wake me up by vinrating on my wrist. When I kept my phone in my bag and go to the kitchen, I can know when there is an incoming call as the smartband will vibrate to notify me. Now I never miss out any call since using smartband!

With the aid of different smartband extension apps, you can remote your phone even better than other brands. Example, when activated the Media Player mode, a single tap after pressing the button of the smartband once, Music app will open and plays the songs! With Smart Camera Extension, taking a Groupfie will be so easy like never! Just press the smartband button and a single tap will trigger the shutter!

Cons

Overall, this smartband has some cons as below

1) Not as accurate as pro tracker like Jawbone Up or Fitbit or Garmin, but since it is activity. tracker and life recording device, I could say it worth the drawback. As even it was not a perfect steps counter, but it still did its job to show whether you are more active than yesterday!

2) Limited functionality, might just for now since no API was available at this moment, this smartband just works for different tasks without allowong you to customize own vibrationpatterns or LED indicating patterns. Without a display was the biggest drawback...But who cares? Even you are notified or able to see the content of message, you still need to take out your phone and reply, so it makes no difference unless you willing to buy the expensive Samsung Gear smartwatch or Apple Watch or others.

3) Remote media player by tapping on smartband was not flawless last time, but with new updated firmware, it works better with some practices. Practice makes perfect!

Extended functionality

The word "functionali-" was not end with "ties" is because by now, there is only an app called Smartband Notifier which is available at Google Play Store which works with Tasker to produce customized number of vibration with customized interval between vibration for different apps' notification. Without display or LED pattern, at least, you can determine which app is notifying you without a glance on your phone.

Suggestion

1) Time feature

Since smartband has three LEDs, I suggest developer to make a gesture like Miband to show the current time. Like example, 1 o'clock, LED A flash once and so on for 2 and 3 o'clock with flashing of LED B and C respectively. Add once more for a cycle like flashing LED A twice for 4 o'clock, understand? And for 10,11 and 12, set the LEDs to flash alternately with combination of two LEDs : 10 (x_x) , 11 (xx_) , 12(_xx). Dividing 60minutes into four quaters and light the LEDs with different patterns to tell the quater might be a simple solution for the minutes.

2) Enhance the media control by flashing the LEDs but not just remain light up to tell the users whether their taps on the smartband are registered or not. A beep sound also can be played on the phone to tells the users that their phone is responding with the taps. Also, adding volume control by movement of wrist as with the 3D accelerometer, the smartband can tells the phone that users is turning their wrist clockwise to increase the volume. This situation is just similar to the game which designed for Smarband (forgotten the name of it, is a bombing airplanes game).

This is my step-by-step reviews and I hope the developer will see these and modify the smartbamd firmware to fully extend its potential to be not just a simple band! Goodluck everyone!
