Review: Fitbit rocks get them all! - So I got my second flex last week, after the first one was broken out of the box. I can't say enough how easy it is to return defective products to desertcart, very user friendly. Now for the flex. I'm totally sold on fitbit, yes I have a few. . I started out with the Surge. The surge is a great product in its own right, but is too bulky for me to wear every day in the hot summer. If you need all the bells and whistles the surge is the way to go. The surge also costs 250.I needed heart rate monitor sometimes because my health sucks. I'm 46 and I've had 2 mild heart attacks and now have chronic idiopathic pancreatitus. I spend a lot of time in bed, but I still need to do some easy physical activity, which for me is walking. Since the surge was too sweaty and bulky for me in the summer months, I tried the Charge HR next. I really like that one too, but it cost 149..but it's alot less bulky and has a great accurate enough heart rate. But it still got sweaty under the wrist and I was worried about it getting harmed when I do my housework. So then I got the flex.. The flex is very slim and can be loosely worn because it doesn't track heart rate.. Which for me is fine for most days when I don't need all the features. So no sweaty wrist, and, you can purchase many different types of replacement bands to match your outfit. The flex does track, steps, calories, miles and sleep which must be turned on manually. The flex also only costs about 80 bucks so I'm not as concerned about it getting wrecked doing heavy duty spring cleaning. The cost also makes it easy to get introduced to fitbit. The software and app are amazing and very social and user friendly. The app also allows you to hook up different trackers and set your goals up for what you want to do. Having friends on the app allows you to compete and stay motivated too. The flex uses 5 LED lights to help you see how you are doing through the day. Each light represents 20% of your goal. For me, I find the lights more motivating than having the raw data on my wrist because you have to work harder to get all the lights and complete the goal for the day. And, unlike the surge and charge that need to be charged every 3 days, the flex only needs to be charged once a week which is a lot easier if you like me have a crazy busy life.. So get a flex, you will love it and the fitbit community.
Review: Great option for beginners not looking to spend too much money on fitness tracking - Great value for money! you can synchronize it with any phone(apple, windows and android). readings are quite accurate and price is not too bad. If you are a beginner to workout then this one is way better than the other options out there. otherwise go for garmin vivosmart.
