Microsoft Band versus Fitbit ChargeHR
I am a long time FitBit Flex user. I had the ChargeHR for about 30 days, then it started making my wrist blister. FitBit was awesome and refunded my entire purchase even though I didn't buy it direct. But as a Windows Phone user, there was only one other choice... and the Band happened to become available again just as I was making a decision.
Fit, Comfort and Materials
The MS Band is a rigid ring resembling a oval with a flat side. The rubber material has a cool, smooth feel. The metal clasp feels firm and reliable. With sensors on both the top and the bottom of the wrist, the wrist can sometimes feel slightly compressed between the two. The thickness of the unit feels somewhat like a bangle bracelet: in the way and "banging" into everything.
The ChargeHR band is rubbery, flexible and a little tacky with a watch-like clasp. It was not as pleasing to the touch, but unlike the Band it did a good job gripping the skin to encourage it to stay in place. Unfortunately, the tacky band collects dust, dead skin cells and fuzz, making it looks old and ugly (and a bit icky) before the first day was out. It also has a history of causing allergic reactions in many people, prompting the recall of a previous model (the Force) that used the same material. The sensor unit and display is a flat rectangle which should have standard watch band prongs, but does not. The sensor unit extended past the edges of my wrists and left two gaps on either side, causing the band to form a triangle instead of a nice, pliable circle.
Winner: Tie. Neither is particularly comfortable for petite users, and I can't tolerate sleeping in either. A slightly wider (but shorter) device would be more comfortable for small users. FitBit comes closer with it's flexible strap, but it has caused bad reactions in a lot of users. Overall, advanced function fitness bands have a lot of room for improvement in the comfort department.
Charging
The MS Band has a proprietary magnetic connector. The FitBit has a proprietary plug. Neither has a cover to protect them. For myself, the charging contacts on the ChargeHR burned my wrist. Even after a month of healing, wearing the band the same wrist irritated those same burn contacts.
Winner: MS Band. The Charge HR plug is difficult to connect while the MS Band snaps right on. The MS Band also charges much faster.
Screen and Information
The MS Band has a full color, customizable screen. The ChargeHR has a black and white text display.
Winner: MS Band. The two are not even comparable.
Battery Life
The MS Band lasts for about two days under normal usage. The ChargeHR lasts 4-5 days.
Winner: Given that the Band does so much more with its screen, in reality they are both solid performers, but the nod goes to the ChargeHR for this category.
Heartrate Accuracy
Both devices use optical technology to read the user's heart rate at the wrist. Some users have had difficultly getting good readings with both devices, but I have been fairly accurate (+/- 5bpm) on both devices when tested manually.
Winner: Tie.
Step Accuracy
Both devices use an accelerometer/gyrometer to measure steps. This method, for a wrist device, is prone to error. FitBit attempts to mitigate these errors by allowing you to manually measure your stride length and input it. The MS Band uses its GPS sensor (which the ChargeHR doesn't have) to make automatic adjustments. FitBit uses "steps" as a proxy for activity, so repeated vigorous arm activity (like weeding the garden or sex) will register as steps. MS Band seems to have taken a very conservative approach and only seems to count actual walking steps.
Winner: Unsure. Both provide consistent results.
Phone App (Windows Phone)
MS Band's phone app is somewhat limited in function but works seamlessly with Windows Phone and does not seem to impact phone battery life. FitBit's Windows app is still fairly young. It does not support notifications to Windows Phone users, does not have feature parity with the iOS and Android apps, does not update the live tile, has difficultly background syncing and significantly impacts phone battery life. What features it has working ties into the web app well and provides more functions, like logging food.
Winner: MS Band, for now. If FitBit catches up their Windows app to the other phone platforms before MS adds new features, the balance will change.
Web Dashboard
MS Band's web dashboard is still brand new. It appears to be solid and reliable, but has limited functionality and does not provide the user insights needed for a healthy ecosystem. FitBit's web dashboard, on the other hand, is mature and feature rich. Prospective customers can also use their web dashboard for free to manually log food and exercise to give it a trial run.
Further, FitBit has an impressive list of working integrations and partners, compared to MS Band's meager list.
Winner: FitBit, by a mile. I don't particularly like the appearance and way the FitBit Dashboard works, but it's all there, even exporting data.
Value
The ChargeHR retails at $169. It has heartrate tracking, altimeter and step tracking. The device itself is fairly basic and therefore has longer battery life, but it ties into a feature rich analytic software. Customer service through email and online is somewhat slow but excellent.
The MS Band retails at $199. It has heartrate tracking, GPS, step tracking, and the other plethora of sensors. The device itself is feature rich and has smartwatch functions, but has a much shorter battery life span. The supporting software, for now, is limited. My experience with customer service both through chat and needing to return one for a different size was very positive. (I do not have access to a Microsoft Store.)
Winner: As a user mostly interest in the fitness band aspect, it's a close call. As a Window Phone user I have to give the nod to MS Band. Those who want the smartwatch functions will do the same. But users who don't need or want the smartwatch functions or GPS should give the ChargeHR a look.
