Rated 2 out of 5 by from Technology Is Not Quite There Yet I have used a Polar Loop and a Polar chest strap heart rate monitor for over a year now. When I read about the Surge I was pretty excited by the combination of features, especially the all-day no chest strap heart rate monitoring. Here's what I found, though: when my heart rate was low the Surge reported it accurately, but during exercise it consistently read lower than my actual rate - sometimes by 7 to 10 BPM low, other times as much as 40 BPM low. I verified this using both the Polar and a 10-second pulse measurement. Tightening, loosening, and repositioning the Surge had no effect on its accuracy. I returned it and have gone back to the Loop.

Rated 3 out of 5 by from Great but one critical flaw, heart rate not accura Got it for christmas been wearing ever since, but its going back because it cannot track heart rate accurately during exercise or even hiking. If it could pair with a chest monitor I would keep it. Pros: It does alot of things very well. Easy interface, great website, GPS is spot on, vibrating alerts, good battery life, great responsiveness to touch prompts, charges quickly, sync well and quickly, fun going through all the data Cons: I got the large and it barely fits my wrist, 6'2" 230. Bluetooth syncing with Android smart phone is spotty I exercise a lot and heart tracking is important to me, during heavy exertion this thing is all over the place.

Rated 3 out of 5 by from Really wanted to like, but too many flaws I waited and waited for the Surge to come out. It had all the features I wanted/needed. The first one I got worked great for about a week, then it froze. When it came back to life, it stopped counting stairs (I hike a "17 floor" hill twice a week and it didn't record 1). Returned it (love REI for returns) and got a second one. Second counts stairs great, but over counts steps. Also brought it with me to do some field work and it counts steps while driving off-road because of the vertical component while bouncing around. All the features I want, but can't seem to get a unit that does them all correctly. Maybe 3rd time will be the charm?

Rated 2 out of 5 by from For a fitness tracker - it's ironic I find it very ironic that the heart rate monitor stops working properly while working out. When it looses the signal, that's one thing, but to steadily read a BPM of ~80, when in reality I'm training at 140+ is just ridiculous. Just goes to show that the HR monitor feature is a bit gimmicky if it's basically "making up" the heart rate when it can't read properly. I admit that it's accurate when I'm sitting at my desk doing work and being inactive, or when walking, but for a fitness monitor to not function while working out is just a little more than ironic. I'm returning it today...

Rated 1 out of 5 by from Not worth the money. HR function is VERY inaccurate. When I'm pushing myself to near max HR, it indicates somewhere around 120-135 BPM...when it even registers. About a third of the time, it doesn't register. I've tried the manufacturer's recommendations on band placement, but nothing helps. Also, the proprietary charging cable doesn't seat very well, so the device rarely charges to max capacity. The screen is also very hard to see and the auto back light function doesn't work well. I either have to leave back light on, or cover watch with other hand to fool the photo-sensor.

Rated 3 out of 5 by from Battery life not 7 days; with GPS only 2-3 hours I've owned my Fitbit Surge for 3 months. I wanted to be able to see my stats without having to look at another device to see my daily progress. I wanted the heart rate monitor and the GPS, too. I've been satisfied with it except: I have never gotten more than 3-4 days of battery life (not running anything on it, like GPS or alarm or notifications, music or lights). Each time I've used the GPS, the Surge went dead within 2 1/2 hours each time. When you charge it, you have to be careful with the cord staying plugged into the watch, as the cord detaches too easily.

Rated 5 out of 5 by from Fitbit improves I didn't think they could improve on their product. Fitbit seems to be more accurate for footsteps compared to the others I have tried. I have tried 9 of them. When I run a marathon they are all within 500-800 feet off. But for daily acivities my fitbits reign. The Surge provides the heart rate accurately and is much less hassle than my strap on the chest HR monitors. I really like the altitude monitor that tracks stairs. Only once in awhile will I have to adjust the wrist band during intense exercise when sweating to re-access HR. Superior product. I lost my older Fitbit Flex during a 20 mile run and yard work that day. Fitbit sent me a new one. Customer service is the best. Couldn't say enough about the Fitbit brand.

Rated 3 out of 5 by from The next update will be 5 stars I bought this product to to replace my Tom Tom Nike+ watch. I wanted to routinely track my heart rate without wearing a separate band. I haven't had any of the issues that people here have complained about such as, gps tracking bpm irregularities. My only complaints are that the battery life is terrible especially when using GPS. It says that the battery should last about seven days; it lasts about 3-5 days. My last complaint would be the proprietary plug to charge it; I have lost mine which means ordering online is the only thing that I can do.
