My husband purchased this for me for Mother's Day. However, I didn't know it was available in silver aluminum to match the cool silver bangle band I purchased separately until I had the black Versa. So back it went to Amazon only to have to wait the the silver Versa to be back in stock because they were back ordered until the 11th, then the 13th, the 15th, oh you get the idea. I can only assume they were back ordered so they could fix those bugs a lot of the early reviews on here talk about. Well, I've had mine almost a full day so I've had a chance to check a few things out.1. Accuracy. Initial reports show this fitbit being wildly inaccurate in regards of heart rate, steps, flights of stairs, sleep, etc.I looked at heart rate first and while I've always thought my resting heart rate was around 60 this device is showing a resting heartrate of 98. Well I'm sick right now and hopped up on tons of Sudafed and cough meds so rather than assume its wrong I manually took my heartrate radially and it was actually closer to 105. So the heart rate feature is pretty accurate.Next, I looked at steps. A lot of people complained that it counted steps as they drove, moved their hands a lot, or even when they were typing. I did all of those things and really didn't experience any more than the standard margin of error you normally see with pedometers in general. The 20-50 extra steps that were logged that weren't really steps are negligible to me when I'm logging thousands of steps per day.Flights of stairs. Versa reports that it counts an elevation of about 10 feet as a set of stairs. So if you're going up or down stairs that are way more or way less than 10 feet then it won't seem accurate. However, I only went up one flight of stairs when I came up to bed and my arms were packed full. It still managed to be able to tell that I went up just 1 flight of stairs. And despite all the moving I did all day those were the only stairs I climbed and the only stairs it logged. So that appears to be working okay.As for driving in a car, I drove all over the place to day and my step counter didn't really change except for when I swung my arms too much dancing in my seat to Justin Timberlake.Lastly sleep. I'm afraid I can't help you there unless I fall asleep at work. I can't stand having anythjng on my wrists or hands while I sleep, not even my wedding ring, so I can't really track my sleep. Sorry.2. Those things addressed, its time to talk about form and functionality.Form: 0HATE the bands it comes with and not because of the pins. The bands are too bulky and masculine for women to wear everyday. I put mine on and I didn't feel feminine at all. But like I said, I got the silver Versa so it would match this awesome bangle band I purchased separately. I've had several people compliment me just today who are shocked that its a Fitbit. I am concerned about the face scratching or cracking so I may purchase one of those gorilla guards for it.3. Functionality: the setup wasn't as smooth as it was when I had that first black one I sent back. The required 3 part update kept failing and I had to switch from wifi to bluetooth. It failed a few more times on bluetooth but fortunately picked right up where it left off every time, even when i restarted my phone to see if that would help. (It didn't.) Finally after about an hour it was good ti go. However, the fitbit app was very slow and had a hard time pushing the clock faces and apps I chose to the watch. I kept getting error messages. I also wasn't too happy with the selection of apps. The driving one looked cool but the fine print said it was a free trial of a paid app. I would have liked too see more exercise or yoga apps or even just more games. Gotta love games.4. Lastly, the buttons and swiping around through screens has been a little hard to get used to. They're a tiny bit confusing but they don't seem too hard to eventually memorize the layout. Overall, I like it. I'll edit my review if things change.
