the switch.....I was nervous about a wrist tracker from stories about grossly inaccurate step counts. I have a very small wrist and found this to be thinner on my wrist than my Michael Kors watch. It is extremely lightweight, and simple. If you are "gadgety" and want more of a watch function, this won't be it for you. All it does is with 2 quick taps shows your progress on the buttons during the day. It will vibrate with calls and texts, and can remind you to move your 250 steps an hour. It has done a good job with sleep tracking, and I must say is pretty accurate with the step count.

Pros:
Extremely lightweight, not bulky and the lavender is a gorgeous color.
Easy to snap on, and can be worn loose or snug.
Water proof-I don't wear it in the shower but put it on right after and don't have to worry about unclipping like my old one when I switch from Pj's to work pants, to workout gear, etc.....Put it on and forget about it (unlike the dressing room I had to go back to 2 hours later after trying on clothes once).
Vibrates with texts/calls/reminds you to move every hour
Easy syncing/tracking on phone-you can't see anything from the band so you have to sync periodically throughout the day from the app. I have my phone all the time so that's not a big deal for me.
Removable tracker pops out easily and can be used in other accessories.

Cons:
No watch/HR/caller ID function
No stair climber function-for some reason I really liked that with the One. Kinda bummed.

Overall I would say this is an excellent product. Since I have a watch and am not a hardcore workout person, I don't need the extra bells and whistles of other Fitbit models. It does the job, and is holding up nicely. Would recommend.

有点:
非常轻巧，不笨重，薰衣草色是一个华丽的颜色。
易于捕捉，并带起来宽松和舒适。
防水，但不要在洗澡的时候带起。
以震动的方式提醒来电、短信。
可移动跟踪器弹出容易，可用于其他配件。
缺点:
没有时间显示，通讯录，没有来电显示功能

总的来说，我认为这是一款很好的产品。因为我有一个手表，我不是一个锻炼着迷的人，我不需要额外的钟声和口哨等。它会很好的为您工作。我觉得应该可以推荐给你。

One of the main reasons for purchasing a Fitbit was for the silent alarms, as my alarm would annoy both my roommate and me in the mornings. Although I at first set backup alarms on my phone, I turned them off as I realized the Flex 2 had very strong vibrations that have never failed to wake me up in nearly a month's use.
A common complaint is the press-on design of the band, and at first, I was disappointed at how difficult it was to put this on. However, after use, it became much more comfortable to put it on, but not to the point where I felt it was in danger of falling off by itself.
Finally, I love the Fitbit software, whether online or on mobile. I like the social aspect, particularly the friendly competitions and challenges. Although this model lacks a heart rate monitor, I use my Samsung Galaxy S7's heart rate sensor in conjunction with my fitbit to track my exercise statistics.

PROS:
Slim and minimalist design
Durable band
Waterproof pebble
Strong, effective vibrations (alarms, notifications)
Software

CONS:
no HR monitor (not truly a con at this price point)
