MIO – Optimise Your Training

Very happy with HR strap, well priced and fast shipping. This is the second Mio I bought and they are great!
Seamless integration with Garmin watch. Easy to use and accurate
Bought to replace the one I lost somewhere after a year of use. Never wear a chest strap again.
Great monitor, I don't like wearing the chest strap, and this works well. I do have to wear the monitor and my garmin watch on the same wrist to keep them connected.
This product is easy to use. It links well to the phone app and Garmin. No drop out so far or misreads from interference which the old chest strap is prone to. Highly recommend. Wife is happy as will not use a chest based hrm
Works well with my Garmin and Iphone. More comfortable than a chest strap.
Great little device, easy to pair with Sony Xperia Z1 and Strava. Battery life seems a little short but I'm not sure if this is early days or not and the Mio link Android software is severely lacking in features compared to iPhone software.
I have used Mio Link for a few weeks now. It works better for me than a regular chest strap which tends to loose the heart rate and needs to be repositioned often. The only caveats for the Mio Link are: I need to wear the strap at the same wrist as the watch to avoid dropouts and the sensor requires to be in contact with your skin to work so the strap needs to be tight. I used the device wearing in continuously for a couple of hours and it was ok. I dont expect that it should be really a problem even on a day-long hike (not tested yet) as the device is very light and the strap is elastic enough.
Only used it for a week but it seems really good. It charges via a small USB charger which connects magnetically. Does what it is designed to do but is more comfortable than my old polar chest strap.
Works very well with iPhone and Cyclemeter app. Slightly less reliable when my skin gets really cold and blood vessels shrink, but overall it's a fantastic product.
Good hr sensor. If you hate chest straps as much as I do it's no-brainer. It caught me off guard once not charged before long ride. I could fit small/medium but I'm happy I went for large - some of castelli gloves (diluvio, prima) are really long and sometimes it ends up high above my wrist. Strava supports it (for Android there's publicly available 'experimental build' - strava labs, no problems whatsoever). I use it with my garmin E500 and Nexus4. It's first of it's kind for mainstream so if you don't need it - no rush as prices should go down when others (and with optical technology I expect everyone will offer HR sensor sooner or later) join club.
Very easy to set up. The MIO go app is not that great but I use it with other fitness apps and it works great. It is very comfortable to wear and much better than having to wear a chest strap.
Records heart rate accurately. Just as good if not better than most chest type monitors. Very convenient.
