I bought this about 2 months ago. I wore it every single day since then and I just loved it! It is basically a motion sensor that detects and keeps track of your daily movements. You can set your own daily goals steps you walked, distance you took or calories you burnt.

I can keep track of distance by using my Garmin ForeRunner 10 (which I reviewed here) but this one is easier to use because it does everything in the background. Garmin takes a few minutes to start because it needs to find your GPS coordinates but that’s not the case for Flex.

Flex lets you keep track of distance, active minutes, calories and steps.

Also you can log your weight, other exercises and food intake so that you can calculate the net calories throughout a time period.

Another great feature about it is tracking your sleep quality. You can use this data in conjunction with your daily activities.

And here is my favourite feature: Alarm! It turns out if something on your wrist start to vibrate you wake up. Instantly! Of course I keep my phone’s alarm still running as a fallback method but this one works pretty good.

Conclusion

I bought it for £68 and as of now it is listed as £83 on Amazon. Apparently the price fluctuates a bit but I think £70 – 80 price range is good for this product. I charge once every 3 days or so. Other than that I completely forget about it while it does its job in the background. It motivates you to reach your goals and be more active in general and the silent alarm is absolutely fantastic. I’d recommend this to anyone who would like to have more exercise.
