Rated 5 out of 5 by from Works Great! I purchased the H7 about 6 months ago and it's worked like a charm every time. I only had one time where I had to take out the battery to reset the unit. My iPhone apps (Runtastic, Endomondo and Runkeeper) had no problems connecting to the HRM and giving an accurate BPM to the apps. The H7 HRM strap does not track mileage or calories (as another reviewer claims) but strictly monitors your heart rate and communicates this information to another Bluetooth device (such as your smartphone or watch) and that device passes the information to the app. In my case, my H7 connects to my iPhone and relays the HRM data to my Runtastic app. I've also connected my Runtastic app with MyFitnessPal app, so that training info is also passed on seamlessly and automatically. I've enclosed screenshots from iPhone apps that I always use: - PolarBeat for actual configuring and pairing of the H7 strap - Runtastic for displaying my heart rate during my workouts - MyFitnessPal for tracking my exercise that is passed on automatically by Runtastic

Rated 5 out of 5 by from Works great with Loop Bought the Loop first and enjoyed it much better than some of the competitors I have tried. I then got the H7. Took me a minute to get the sequence right on hooking it up through my loop and not using the cell app. Oonce I did that working in combo with the Loop has given me my best info on my work outs that I've ever had. Knowing my heart rate constantly without having to look past my wrist and then being able to upload my Loop to my cell phone when I'm done gives me instant info to know how beneficial my workout was. I recommend using the H7 with the Loop to give great feedback and help you get your work out more productive.

Rated 5 out of 5 by from Excellent, works the way it should. Like most people, I purchased this product to communicate directly with my phone. I also had similar connection issues the others had. These issues were occurring because I was also using my bluetooth headphones. If I used wired headphones, the issue did not occur. Fact #1 - This device only sends out a signal. Your phone is responsible for making the connection and remaining connected. Fact #2 - The bluetooth standard is not designed to support multiple devices at one time(sometimes it worked and sometimes it didn't). My solution? I purchased the Polar Loop to track my fitness and cardio while my phone plays music and tracks my route with GPS.

Rated 3 out of 5 by from Awesome Watch, Heart Rate Monitor H7 Issues I brought the polar heart rate Ft4 loved it, then went out and brought the FT7 and loved it, so I decided to buy the H7 Bluetooth monitor and it had been going great. I have only had it six months and lately it keeps losing the signal. I have followed the directions from the video about the care of the strap and monitor. I have had to change my battery twice a month, and now the battery is not even lasting two weeks. I am so mad because I have gotten spoiled with linking it to my fitness apps and now I am back to using the regular monitor and keying in my workouts by hand. Such a shame, because I really loved this product.

Rated 5 out of 5 by from Works like a charm! I have had my H7 for 2.5 month's now and I use it 3-5x a week and it has not missed a beat (pun intended) ~ so well in fact that I have purchased the Polar Stride Sensor and I have no issues with both connecting with my iPhone 5S and staying connected. I recently returned my Garmin Forerunner 220 because the material for the strap for the HR Sensor was folding over on itself and pinching me on runs. Thank you for attention to detail Polar!

Rated 1 out of 5 by from Great idea poorly executed I got this about a year ago and absolutely loved it. It would track my mileage, calories, etc just like the watch, but having it speak to me as i was running was awesome! Especially as the displays on the watches are small and hard to read without my glasses. Then one day it just didn't perform consistently. I'd be running like a mad woman and the monitor would state my heart rate was at 56. Then it would have it at 186. Then zero. I changed the batteries often, kept my heart rate sensor clean, and still couldn't resolve the issue. Such a bummer for such a great concept. I also bought the Polar Beat upgrade and when i upgraded my phone, the upgrade didn't follow. Was definitely not happy with that as not sure why i would need to repurchase. Would love to see this product evolve!

Rated 5 out of 5 by from Best heart rate monitor I am not sure why some of these reviews are so negative. I have had the H7 for about a year now and have not had any problems with it. I love keeping all of my stats on my phone to help me make goals for myself and I can visually see when I am making progress. My heart rate has been consistently read (unlike a previous review). I have had no problems with my connection to my iPhone 5. I also really like having the GPS on the monitor/app. Other GPS monitors tend to be fairly expensive. I also like that iit syncs with most fitness equipment. It automatically syncs to the spin bikes in spin class so I can monitor how I am doing. There are a few downsides. One, you have to have your phone close to you when you are using your monitor. This means you have to carry your phone around with you in the gym, which I hate. Two, it does not sync to myfitnesspal. I am sure this is something they are working on though since there are many complaints about this. Three, when I bought this in the store, I did not have size options for the band. I have a fairly small ribcage so the standard band does not fit snug. I have to tuck my monitor under my sports bra and sometimes the does not keep it up. I am not lowering my rating for this because I have this problem with all heartrate monitors.

Rated 1 out of 5 by from Don't bother - won't stay connected I have had a "regular" Polar Heart Rate Monitor for years and been very happy with it. I was excited to be able to integrate all my fitness devices with my phone so I got the H7. After several attempts, I got it to pair with the phone, but it has been flaky since I got it. I'll start a workout and the phone/sensor will be connected. But it drops off during the workout. It is NOT due to improper connections or bad conductivity from the strap, because I still get a full signal on my old Polar watch. I'm a tad irked to have spent all the money to get a new HRM that really only reliably does what my old one did. (OH. And for anyone who can't get the Bluetooth signal to work at all... try the "short the leads with a paperclip" trick that has been recommended by reviewers on Google. Lousy way to have to reset an expensive product.
