GREAT motivation for getting fit

12 years ago
I'd bought the earlier version, the Fitbit Ultra, to help with my quest to FINALLY lose those last pounds to my goal weight. This is what it took to help make a former couch potato a walkin', exercisin', movin' fool. But my Ultra died due to sweat contact (who was the genius who didn't think to make a pedometer sweatproof???). REI easily and quickly replaced my dead Ultra with the new One. The One unit itself is smaller and lighter than the Ultra, but unlike the Ultra, isn't a "clip" shape in itself. So unless you put it into your pocket, you'll need to use the included clip - making it about the same size as the Ultra in the end. However, the big differences (and bonuses, IMO) are: a) it's sweatproof (yay!); and b) it has a fantastic little vibrating alarm which you set via the desktop software. This keeps track of every step I take, every floor I climb, every calorie I burn, AND the quality of my sleep. I love that it synchs automatically with my computer, now via a TINY little dongle that lives in one USB port - and the charging cord it tiny as well. It charges VERY quickly and the charge lasts about 5-7 days,in my experience. My motivation comes from the goals I've set myself - 10,000 steps per day and at least 10 flights of stairs per day (you can set anything you want)...if I don't reach my goal for the day, I find myself making sure I walk around my house, if necessary to get my steps in! I now average 70,000 steps per week (time to up my goal!) - I used to average less than 20,000 (I told you I was a couch potato!). I also wear it on the included wristband every night to track my sleep - and that vibrating alarm, which I was sure I'd sleep through, REALLY works well!! Very quiet (not really "silent," but it's unlikely to wake a partner like an alarm clock would) and it really works! I set alarms throughout the day to remind myself of things like taking vitamins, appointments, etc. It's more handy than I'd expected it to be. The only drawback with this device is that it IS essentially a pedometer - so activities that don't involve step-like motions aren't recorded totally accurately - things like Zumba (doesn't count any arm movements), spinning, biking, etc.). You CAN overcome that by logging those activities into the desktop manually - but in it's next incarnation, I'd love to see that improved. But for me, that's a relatively small drawback and easily overcome with minimal effort. I love (and depend on) my Fitbit so much that I've literally turned my car around and gone home when I forgot to put it on in the morning...

Things I wish I'd known BEFORE buying
SpanielMum

I went through about five Fitbit Ultras before getting the One. All the Fitbits have a lightweight, useful design, track steps accurately & can be used to figure your overall activity & challenge yourself to new fitness goals. But..... Fitbit One suffers from the same type of problem that the Ultra did - the peripheral support details are HORRIBLE! Probably most frustrating to me is that I bought this device to have LESS work, when, in fact, it creates MORE work. The only way you can USE the information collected by the Fitbit is through the Fitbit software- and getting to that software is now going to consume almost an hour of your time, every day, despite your best efforts. Do you have a spare 40 minutes a day to troubleshoot your laptop, your android phone, the Fitbit dongle and the interface? I don't - and I'm tired of trying. The software that you download takes priority in my laptop routine, so it comes up first - BEFORE any other software has loaded, and it hogs the operation until it's done - but it's never done. One consequence of this is that my laptop has not connected to my WiFi until AFTER the Fitbit software has loaded, so the Fitbit software ALWAYS tells me that I have "No Internet Connection Found." This necessitates removing the dongle, taking down ALL other programs and reloading the start - and you get to do this again and again and again and again and again and again and again and again and again and again and again and again. You do have other options. You can RELOAD the software, but you must first carefully remove it all first and download it again. Fun? I don't think so. I've had the Fitbit One about a month now and I've reloaded the software six times, spent 40 minutes a day syncing or attempting to sync about six days per week on average, have downloaded the Android phone version and found it to be as useless as the laptop for syncing - again, the same message over and over, that "No Internet Connection Found" To top it off, it then very neatly goes ONTO the internet, straight to the online help section where you can read the instructions one more time BUT YOU CANNOT SYNC! That's right - you're online, but your software tells you it cannot connect to the internet. No kidding. When I had the Ultras, I found that actual, bonafide Fitbit support was scarce. The clip would break, I'd email them, they'd promise another within ten days, five weeks later I'd email for a status and they'd tell me that their supplier had changed and it was an inadvertent error and they'd send another. Replacement parts took 8-9 weeks to arrive, on average, IF they ever did, and were all just as poor quality as the original peripherals. Why have an expensive device with 39 cent clips and USB ports whose wires don't last two weeks? Another thing I've noticed about the One is that the USB charging cable, while more reliable than the prior USB sync port, takes far longer to charge the Fitbit than the product information claims. Mine takes about two hours and must be done about every five days - not exactly the quick, once a week charge they claim. Bottom line: this is a useful, innovative device, but it's relatively expensive and full of bugs. You will be the beta tester for this product - and whether you find it helpful or frustrating, it will test your patience and resolve.

Just What I Wanted!

11 years ago

I'm not an exerciser, but wanted to know just how much (or how little) I really do move about in a day. So I bought this on the recommendation of a friend. Set it up online and on my iPhone. First day out, I lost it! Had it clipped to the waistband of my pants and played a round of golf. Must have come off in the restroom when I was taking off a few layers. One of the staff found it and within 24 hours I was back in business! Now I wear it clipped to the inside of my bra! I love the sleep tracking feature (provided I remember to turn it on and off at night. I also really love the regular emails that give me a recap of my week.

I needed something more

12 years ago

I gave it a try for a month but felt that I needed something more. It was accurate with the running and walking, but did nothing for me with hiking, rock climbing, biking. Calorie count was totally inaccurate as I had to put in my own estimate for aerobic classes and other activities. I decided I needed a heart rate monitor and GPS and didn't want to wear both.....I think it's good for people who are generally trying to push themselves to do a little more throughout the day, such as walking and stair climbing-but if you are into a lot of different intense activities I wouldn't recommend it.

Motivating but fell off easily

10 years ago

I don't usually review products, however I am so frustrated with the situation that I must. The product itself worked great, but I do recommend charging it fully before the first use (it comes about 1/2 charged and then starts blinking and not recording steps when it needs to be recharge). I used it faithfully for a week and gained great information about my daily movements, however it fell off randomly one evening while out to dinner, and it is lost. I had secured it fully upon attaching it to my pants (as I had for the past week), but when I returned home 3 hours later, it was missing. There needs to be a better method for attachment to prevent this from happening!

Great product!!

11 years ago

I love this product!! I have suggested it to my friends and family. Most of them have one now. I never really use the gym, but run/jog the streets and local stairwells on an almost daily basis. This product helps me on days I don't feel motivated...I look down and see a low step count, low very active minutes, or low floor count and I know I can do better...I hit the streets!!! The sleep tracker also made me realize that I needed to focus more on appropriate amounts of sleep. My first four weeks, I averaged three to four hours of sleep a night. This week I averaged seven hours a night.

Better for me than the Flex

11 years ago

I used a Fitbit Flex for several months until losing it during a cross country trip. After missing the tracking for several months, I replaced it with the One. The counts seem to be more accurate for me; I conjecture that the arm movements and steps are harder to distinguish on the Flex. Also, there are quite a few stairs where I live and work, and the Flex didn't give me credit for climbing them. Last, clipping it to my belt is more comfortable to me than wearing the Flex on my wrist. (I gave up the sleep tracking feature of the Flex partly because I didn't like wearing it to bed).

Great, but requires internet to sync

12 years ago

I was in love with this product until I discovered that I had to have internet to sync it and change alarms. It is very accurate both on steps and stairs. I loved the ability to sync with my phone and track my history. I also bought it for the silent alarm function. I became very disappointed when I found out I couldn't sync it even via bluetooth with the app on my phone without an internet connection and that included changing the alarms. It makes no sense to havee an app that then requires you to also have an internet connection but I even verified it with the company.

Not impressed with the Fitbit Obe

12 years ago

I'm not impressed with the accuracy of either the step counter or the stair tracker. Both can come up with widely different results for doing the exact same course. The alarm works when it stays on my arm. But I wake up regularly (LATE) and find the armband has come off my wrist during the night and is hiding under my covers somewhere. It does stay nicely attached to my bra during the day. The one very positive thing ... my 7 year old son is infatuated with seeing how many flights of stairs he can do daily. I'm going to be returning this.

Love my Fitbit!

10 years ago

This is my second one. I lost my first one. Either I misplaced it or it fell off my belt. For a month, I kept hoping it would show up. When it didn't, I used my dividend $$ to buy another; I missed it that much. It really does help me get my steps in. There are some days when time and my job just doesn't allow for 10,000, but most days I can get there. I also like to track my sleep. I'm just not sure how accurate it is. If it is, even when I think I've slept well, my Fitbit shows that I toss and turn. Maybe I need a sleep study. Regardless, I am addicted to my Fitbit.

how to not lose this handy counter

10 years ago

This is my third fitbit one, I lost the first two traveling around in the busy Tokyo crowds. Either the clip holder let the fitbit slide out, or the whole fitbit and clip got rubbed off my pants pocket. I don't think we need to discuss the many uses of this item. How to not lose it? I attached a 7/8" key ring to the fitbit clip, and then a pocket watch lanyard from the fitbit to my belt loop. Problem solved so far.

Don't loose it!

11 years ago

This is a replacement for one I lost that I had been using for about 3 months. It simply unclipped from my pants and is now lost. I now use a make shift safety lanyard with an aligator clip to doubly attach my Fitbit to my pants. The sleep monitor is interesting but I am not so sure about its accuracy. It supposedly provides time awake, asleep, and restless movements. I think the data is helpful to compare from night to night to gauge sleep quality but I am not sure it is that accurate. Otherwise, I am pleased with it. Afterall, I bought a second one to replace my lost one.
