The Fitbit Alta is about as chic as fitness trackers come. And the equally chic Alta HR ($149.95) adds continuous heart rate monitoring and better sleep tracking to the mix in order to close the gap between it and Fitbit's more hard-core offerings.

Long battery life; More in-depth sleep tracking and insights over its predecessor; Accurate heart rate and step count readings; Slim and comfortable to wear 24/7 with plenty of band options

Screen is occasionally unresponsive; Buckle feels a bit flimsy; No altimeter; Lacks GPS

I was given one for Christmas and I love it! Only problem with these fitbits is the bands tend to come loose or undone. I lost my fitbit because of this, I would definitely recommend getting a one of the other bands that actually has a clasp.

I really like this fitbit. It's relatively discreet so it's not bulky and I like how slim it is.The features are great and are really helpful when synced with the app on your phone.

Fitbit makes good fitness trackers, but so does everybody these days .You can buy an AUD$20 fitness band from Xiaomi and it will count your steps with a reasonable degree of accuracy, or you can buy a AUD$500 Apple Watch and it will also count your steps with a reasonable degree of accuracy.

Looks great; leather bands are great; Fantastic battery life; Polished companion apps

Premium price; No water resistance; Slow to respond screen

I have had this fitbit for a month now. I purchased it primarily to get a gleaning of my sleep patterns, such as REM and deep sleep stages. I was pleasantly surprised at the detail provided by the fitbit in this area, particularly the many 'awake' stages occurring during my sleep which might be...
