H303 Heart Rate Monitor

This is a long term review after owning two of these.....my first one was lot on a cycling trip.The HRM and strap are very well made and robust for the price. The branded alternatives from Garmin, Wahoo....etc. are way more expensive and essentially do the same thing.The HRM connects with watches, cycle computer head units, and indoor trainers. I often train using power and HR Zone's and I find that the HRM keeps a pretty good and accurate record of where I am at. Although I am not an olympic standard athlete by any means.The only thing to consider when buying this HRM it that , compared to some of the other HRM I have owned, I found that the battery doesn't last as long in this model than others. I have found that I need to change it every 3/5 months. It is a minor issue but worth considering.

Heart rate sensor arrived with the battery already fitted. Just attach it to the supplied elastic belt, wet the back of the belt, put it on and press the Bluetooth button on the ProForm treadmill and it was paired within a few seconds. Status LED on the sensor only flashes a couple of times when you put it on, but useful to check battery condition. Heart rate value is received and displayed in the treadmill. No issues with intermittent comms, just works perfectly. Remember to remove the sensor from the strap when you're done to save the battery life. (No off switch.) Info was also displayed on the ifit app on my ipad, so didn't use the Magene app.

HR seems accurate and the band is pretty comfortable for long rides. I have issues getting it to connect to my GPS if I don't put the monitor on while my GPS is already on and nearby, so maybe user error but it would be nice if the HR monitor attempted to connect more often.

Worked well for the first 10 months and appeared to give reliable and reasonably accurate readings. However the unit then started to have connection issues and the readings became wildly inaccurate.New batteries have been tried on multiple occasions but have made no difference.In conclusion this has been a waste of money. The unit is so inaccurate that it's unusable and as it's now more than 12 months old it's out of guarantee and can not be returned.

I've used this for several weeks and it's worked just fine, and seems every bit as accurate as the Polar H7 it replaced.Build quality feels good, certainly for the cost, and I've had no issues with connecting or drop outs, plus the strap seems to be of decent quality and widely adjustable to suit a range of chest sizes.Highly recommended!

Worked well and did what I needed it to by linking with Strava to track my heart rate during workouts. However it stopped working after 5 months ( gym sessions twice a week so nothing to harsh). Changed the battery but no joy. Ok for the money but can't recommend as didn't last long enough.

It works as it should

Bought this to replace an old Garmin unit that wouldn't pair via Bluetooth.The Magene works flawlessly, it's accurate and the connectivity is brilliant, I can pick it up and it won't drop Zwift connection even if I'm off the bike in a different room.I also have the cadence and speed sensor by Magene, which is why I bought this HRM.Genuinely great kit from Magene, would recommend to anyone.
