I bought this when my FB Surge 2 bit the dust. Not that it really died, but the band finally gave way, and can't be replaced. I've had the GearFit for a few months and still trying to get used to it.
Yes, it is cool looking. At a glance, I can read the screen easily. There are a lot of options and customization. Built in GPS and the bands can be replaced. Those are the primary reasons I bought this. I'm not a runner, but the GPS tracking is a must for cycling.
Built in WIFI. After walking, I like seeing the steps, time and MPH. (who knew that I could walk so fast?)
But for the few months that I wore this (bought in middle of winter, then never got around to having the bike tuned up), there wasn't any cycling so I can't comment on how well the GPS works. While walking, the GearFit will pick up on the activity, and if I glance at the face, it shows the activity time. This doesn't really help me, I'd prefer to see the steps at a glance. Again, I am sure that this is something that I have to customize.
But that battery life! Went for a walk yesterday and realized yet again that I wasn't wearing it because it was at home sitting in the charging cradle (where it spends a lot of time). Seems like it has to be charged at least every 3 days. Ideally every other day, before you get the low battery notification.
Activity tracking is not as good as my FB, or maybe it's just different. Spring and summer is lots of mowing (not a riding mower). 1 piece of mowing is around 5000 steps, the other two are around 7000 steps each. The FB would capture these steps, and pretty accurately, too. I know because I had someone with a Samsung tracker follow me around while mowing and we both recorded the same number of steps +/- 200 steps. The GearFit just says "other activity" or something like that, and does not capture the steps. I think I could probably push buttons on the tracker and tell it to capture my walking, not sure about this, but even if I could, I don't think that I should have to.
Pairing with Samsung apps on my iPhone is a manual and tedious process. FB would constantly sync if I set it up to do so. The Samsung does not. In order to sync, I have to open the app on my phone, and make sure that my GearFit display is on. My SO tells me that there is no trouble with constant sync, so apparently this is something that is unique to me, another setting that I might have missed.
For casual activity (ie, not a hard core runner), I think that this tracker is great for the price IF you don't mind the battery life. And if I could remember to charge it every other day, instead of realizing at the last minute that it's almost dead, I probably wouldn't mind.
After doing some browsing, I was going to give this away and possibly go for the Garmin Forerunner 35 or 235. But not being a hardcore athlete, I am going to play around with it some more and give it until the end of the summer.
