Somewhat difficult to read outdoors
Draws relatively much battery
Feels well constructed
+ Syncs to Google fit which I think is a huge plus because you do not get locked up with any provider.
+ Can sync with heart rate monitor.
- Poor battery life, you train you have to recharge every few days, or else at least once a week, and sure as Amen in the church forgets to put on tape again.
- Sleep tracking is so bad that it could be taken away, If you go up and on the example mug and then go to bed again not understand it that you fell asleep on. Pretty hopeless if you have young children.
The summary is that there is a great product, but I would still say that it (and probably the sequel) is the best in its price range (over £ 1000).
Had my now around 6 months, and I like this model. It fits like a glove on the wrist. Easy to use and understand. A couple of minus is that you must download at least every other day, sometimes after only one day. Noticed an error for a week and it was that it got kind Tuppjuck out on the lake when you were on a boat. According to the pedometer so I had taken 35,000 steps a few hours :). A minus to the actual sync that can mess up a bit ,,
A little update:
Because of poor battery life so I contacted the Polar and sent back the tape, about a month after purchase.
Lowers the grade of "good" but thank Polar for very good customer support.
Took delivery of my Polar Loop for almost a week ago.
It was very easy to get started and even heart rate belt (Polar H7) worked directly
The thing that made me choose Polar LOOP against the other "life-tracker" bracelets was that I wanted a bracelet that worked with chest strap, because I train 3-4 times a week.
This is a really good evaluation of the Polar LOOP, Polar Loop In-Depth Review http://www.dcrainmaker.com/2013/12/polar-depth-review.html
It felt very difficult to cut off the bracelet so there will be the right length for my wrist, but it went well. However, I was cut in three installments before it sat optimal :)
I gave 845: - for LOOP and 699: - Pulse band H7 (directly from Polar)
Works with chest strap
Stylish (my opinion)
Works very well against the app in my iPhone 5
Do not need to sync with your computer (other than the first time, when it also updated software)
Good, clear display
Capacitive button works well and does not tear (connector on the back must sit against the skin, otherwise the button does not work)
Short battery life is about 3 days for me (practicing part)
When the bracelet comes in contact with water, the display lights up (as if you pressed the button) no immediate problem, but it draws a portion battery.
Although the LOOP and chest strap H7 is waterproof does not my mate pulse in the water, due to the Bluetooth SMART does not stuff it.
Do not measure how many stairs you passed (like Fitbit)
Is a little unsure of how exactly the pedometer is, but it is not so important for me.
There is no start or stop training with heart rate monitor, but the measurement starts when the heart rate belt is put on the body.
Feel so far satisfied with LOOP
