Rated 5 out of 5 by from works great, easy to put on/take off I bought this almost 2 months ago and have been very happy with it. I have had no problems putting it on, nor have I had any problems with tapping the display or turning my wrist to get the time to display. It's definitely not as sensitive as an iphone screen, but it doesn't claim to be. Strong taps work every time for me. It also feels secure on my wrist. As others have mentioned, it doesn't count your steps, but that's not a huge deal for me. I have small wrists, and the small size fits well. I was waiting for fitbit to come out with a smaller/sleeker version that also had a watch function and this fits the bill. I have also enjoyed the silent alarm function.

Rated 2 out of 5 by from A bit disappointing I previously had a Fitbit One that I was happy with and was looking forward to the Alta as a stylish upgrade. Although the Alta looks nice, the Company implemented a couple of key takeaways. There is no altimeter in the Alta, so unlike the One, you will not know how many stairs you climbed in a day. Not the most important metric, but a nice to have. The key disappointment for me is not being able to read the display in daylight. The Company is charging an additional $30 for a product, that while it looks nice, and does the basics, it has, in my opinion, some big flaws for the additional price. In my opinion, the Fitbit Alta is a great product at the $99 price point, but a bit of a disappointment at the $130 price point.

Rated 3 out of 5 by from Nice design but needed replacement I have worn both the Fitbit Flex and the Charge for several years. Both of these worked well but did not have the style I was looking for. The Alta does have styling but it came with problems. The touch screen is insensitive to touch and requires 5 or 6 taps to turn on. Turning the wrist to activate the time works about half the time. The wristband is very difficult to close. You need strong fingers. Unlike the Charge which would fall off without warning hours after I put it on, the Alta seems to stay on; but a simple buckle would have been easier to use and more secure.

Rated 4 out of 5 by from Very satisfied so far I love the look and feel of the Alta. At first I thought I would not be able to do up the clasp at all but after 2 days I could snap it in place quickly and easily. I love that the battery lasts for 5 days. Yes, the screen is hard to read in bright sunlight but no different than the screen on my camera and iPhone. I wish the notification and reminder vibrations were a little bit stronger as I sometimes don't feel them but I do find that the longer I have the Alta, the more often I do feel them. I also love the reminders to move. I have gladly exchanged the stair counting of my Charge HR for these reminders. I do miss the heart rate counts though.

Rated 3 out of 5 by from Wanted To Love It And Almost Did I love the look of this Fitbit...sleek and versatile. But as much as I wanted to keep it, I traded it in because its band closure design was so difficult. I could get it eventually, but never quickly. Would it have gotten easier in time? Who knows. I wasn't willing to risk it. A couple of other things to note: (1) the display is not visible in bright daylight (2) the text alerts are hard to catch and if missed, gone forever (3) the larger display is nice, but it does create a larger hard/bulky surface area which while barely noticeable during the day, was for me uncomfortable at night. One last thing...after the first thousand steps, the display only changes every thousand steps. It's still counting, but you have to look at the app to get the exact count. This isn't a biggy for me, but I thought it worth mentioning.

Rated 4 out of 5 by from I like it! I am pleased with the Alta. The interchangeable bands are a big plus for me. It is true that the tapping is inconsistent (thus the 4-star rating), but for me the display does come on with a wrist raise about 90% of the time. It hasn't been uncomfortable for me, day or night. Note that it will show the exact number of steps if a horizontal display format is chosen. I was formally using the Fitbit One - I think for the extra $30 for the Alta you get a lot.

Rated 5 out of 5 by from Fashionable Fitness I absolutely love my new Fitbit. It is comfortable, doesn't look bulky on my wrist and is responsive to taps and the flick of the wrist movement. The only downside is that it doesn't track stairs but it appears to be extremely accurate and the sleep tracking function is really awesome. The app pairs very well with the device providing accurate and easy to read information.

Rated 1 out of 5 by from Tapping problems Don't buy the Alta. Just bought two yesterday. We're taking them back later today. Tapping doesn't work. Have to tap the screen up to 8 plus times to get the screen to come on. Have had other Fitbits, no issue. The Alta will have many returns because the quality of the interface with the tapping does not work correctly. Strongly, strongly suggest not getting the Alta. If you like Fitbit, like me, choose another model!!!

In addition to walking/running etc, I bike regularly.  How will this track my cycling exercise?

Asked by: ssmqt
I went for a bike ride with this on recently, and it did pick up on it and recorded the activity as biking.

Is this FitBit appropriate for kids?  I wonder if it will track accurately for a 10-12 year old?

Asked by: grittyone
This activity tracker will function properly on kids ages 10-12 with an appropriate size band.
