I've been using the Mio Link for the last 1.5 weeks, paired with a Garmin 910XT (both bought using REI dividends). The ANT+ signal isn't supposed to travel far enough underwater to be usable for swimming. However, in my case the 910XT DOES pick up pulse info from the Link during swims, with the two mounted on the same wrist (the Link goes right next to the 910XT). The pulse info has been accurate for swims. It's worked well for cycling (I hit 36 mph in the Ohio University triathlon and the Link did fine) and runs, including a maximum pulse of 173. I tested it against a chest strap reporting to a different device, and the pulses were virtually identical, with the Link about five seconds behind at the most. Only a few anomalies so far: Pulses were reported inaccurately high briefly near the start of one training ride, and while running from the pool during the first transition of the O.U. race. And there have been a few dropped segments, mostly while testing the Link for sleep (but fewer drops than when wearing a chest strap for sleep) but occasionally while riding or running (when I notice loss of signal, I just push the Link higher up the arm to make it tighter). One caveat: If you wear it tight, the strap will leave a definite mark on your wrist for a few minutes after you take it off. The tightness hasn't bothered me, but for an Olympic-distance or longer triathlon you might want to move it to the other wrist after the swim. My Link takes about two hours to charge, and it runs eight to 10 hours per charge. I'm a perfectionist and I expect a lot from products. The Link hasn't disappointed me.

Cool idea, lacking accuracy for me

I pre-ordered the device with very high hopes I could ditch my old heart rate strap(s). Over the years I've been through various big name soft strap models -- each seems to die with erratic static induced spikes eventually! I think I tried 4 different manufacturers straps until I went back to the older rubber / plastic style chest strap! After receiving the LINK I paired it to my phone through BT and also to several of my ANT+ devices -- FR 610, Edge 800, vivofit, for example. Recording of data with any of these devices was really no problem. Why such a bad rating then?! Very often my numbers don't make sense. With enough HR recording over the years I have a decent feel for where my HR should be. I may not know it to within a beat, but certainly I am usually within 30... unfortunately the MIO often is not. I eventually recorded an old HR chest strap simultaneously with the MIO for several exercises. I did a treadmill run, outdoor long run, indoor spinning session and several outdoor rides. Nearly every time I had periods of completely wrong data -- 20-30 BPM off for minutes at a time. This, to me, is just unacceptable. I've even tried different arms, different locations on my wrist and tightness variation. Some places do seem to work better than others, but I haven't found one that works reliably enough, and always playing with the location is annoying. Also, if the device is too far (read... > 4 ft?) away from the recording device I see occasional signal drops -- HR to "---" or 0. I can't say the distance precisely, but if I don't use the same arm, then I see between 4-5 drops in an hour. There have been rumors that MIO may be working on a software update, perhaps that has a shot at fixing some of the issues, if they do not... mine is going back. From reading reviews from others it seems that the device can work for some people, yet I cannot give it a recommended rating for what I have experienced in my use.

Couldn't be happier

10 years ago

I have only used this once so far on a 25 mile bike ride but it is so much better than the Timex and Garmin chest straps I have used. First of all it eliminated the discomfort and chafing of the chest strap which is big win. Second it doesn't drop out or give erroneous readings (200 bpm while riding easy) like the Garmin chest strap did and I would have to stop and reposition it. I don't get the complaints of having to recharge it and the 8 hour battery life. My bike rides are never longer than 5 hours, then you drop it into the charging cradle when you are done, whats so hard about that? My Garmin Forerunner needs to be recharged after every ride anyway. Its better than finding one day the battery is dead and having to find one to replace it.

No more chafing or licking!

10 years ago

I bought this produce a month ago and it's been great. I've been using it with a Garmin 210 and wear it on the same arm. At first, I felt a bit geeky, but it's worked well so I don't mind at all. Out of the ~16 times I've used it so far, it's only been wonky once, when I didn't have it tight enough around my upper wrist. Once I tightened the strap, it seemed to work a lot better. I did go on one run with my old Garmin HRM just to make sure the readings were consistent, and I was happy to see that they were spot-on. Pros: extremely easy to use, reliable readings, comfortable, no chafing, no need to lick or wet the electrodes as it uses light technology. Cons: it can seem a bit tight at first but that goes away; it leaves marks on my wrist for up to an hour after my run, but never enough to bother me; it's not great on its own -- I wouldn't want to depend on the flashing light to tell me what zone I'm in; the app sucks; it's pricier than the Garmin HRM; no memory on its own (you'll have to pair it with another device or app) Overall, I'm very pleased with the Mio Link when paired with the Garmin 210. I had to give up heart rate training last year due to really bad chafing, and the Mio has allowed me to return without worrying about scarring myself!

Excellent alternative to a traditional HR strap

10 years ago

I was about to buy a traditional heart rate strap when I discovered this heart rate band. I'm very happy that I decided to go with the Mio Link! It doesn't feel obtrusive like a traditional heart rate strap. The Mio Link is comfortable to wear and lightweight. It feels like you're wearing a small watch; you hardly notice it. The device immediately synched up with my Garmin Edge and Garmin Fenix and provides accurate data. There is no display on the Link, which I like. There is a single LED, which turns off when charging is complete and also changes color based on heart rate zone. This is an ingenious feature; I love that I can see what zone I am in simply by taking a look at the color of the LED! You can customize the heart rate zones if you download the free Mio app. Highly recommended!

No more chest straps

11 years ago

I have had issues in the past with chaffing and chest straps. Also during races often my heart monitor would start to malfunction. So far I haven't had any of those issues with my MIO. I use it with a garmin 910xt and it works flawlessly. There was one time that I did get erroneous reading, but it was due to not having the band tight enough. With a small adjustment and the problem went away. I am super happy with it.

Rarely works

11 years ago

I would love this product if it worked, even 90% of the time - but it doesn't. I've used this on a dozen rides and runs so I'll tell you my experience. 1) First run - had to move it around until it sync'd. Then noticed it would lag or just not update. 2) Later runs and rides. I would move it around to get it to sync up - sometimes minutes into my run. Then bad data - graphs of my heart rate would show a jump from 130 to 170 minutes into a hard climb (not a gradual increase, just 130 same exact number for minutes on end.) 3) False readings - I know my heart rate from years of training. But mild runs at 90 bpm - nope. After readjusting it several times, it would jump into 125ish (my usual rate). 4) Even when it works, you can't count on it staying working. It will drop out for no apparent reason. If you use a heart rate monitor to train, to build cardio or for interval training I cannot recommend this. I plan to return it for a replacement and hope mine is just defective. PS - REI is awesome.

Lose the Chest Strap and Get More

11 years ago

Unlike a chest strap which only transmits, the Mio Link also has a range-based feedback LED light. Transmits to Bluetooth and ANT+ devices with ease. Pros: - comfortable after 2-3 minutes though snug at first - light - accurate reading - unaffected by sweating, duration of exercise or skin color (we've shared it as a test) - Good battery life. I let it stay on and connected via bluetooth to RunMeter for five hours and the 30% battery-remaining indicator would still not get triggered. I get over 8 hours of use on one charge. - Connected easily with RunMeter/CycleMeter. Also connected with MapMyRun, though RunMeter has more analytics for the heart rate data. - Adjustable zone settings with the Mio Go app - No cumbersome, sweaty, chaffing chest strap - Range/Zone feedback makes the device useful even if you are not connected to a bluetooth device. Cons: - LED light does not blink frequently enough and needs a firmware update. Can't look at my hand for 8 seconds while running on a trail. - Takes 2-3 tries until you find the correct wearing position. Once you do, you can even wear it upside down (face on the inside of the wrist), or even on your ankle. This would be a solid 5 star product wear it not for the infrequent blinking of the feedback light, which is easily fixed with a firmware update. If you wear it loose like a watch, it won't work. Read the manual before so you know how to wear it. Also, it takes 10-15 seconds to begin to read accurately. I tested it against Polar, and they were more or less +/- 2bpm throughout the test. Improvements: - Mio Go should display battery status, like many bluetooth devices are able to, but does not.

Good for those looking to use while running

10 years ago

I bought this monitor because it has no annoying chest strap, yay!! However, I quickly realized that this monitor is not as accurate as those with that annoying chest strap. This HR monitor is great for simple activities like hiking or running but if you are taking fitness classes that involve your arms above your head forget it. The second the arm with the monitor on it goes above your head you HR drops giving you an inaccurate read. It will eventually recalibrate once the monitor is down by your side but if your looking for accuracy on calories burned or max heart rate this is not the monitor for you. With that said for those looking to use for activities like running or hiking I think you would be happy with this device. Another small piece of advice - make sure the strap is tight; Not cutting off your circulation, but it should not slide freely. Placement is also important. I found that right above your wrist bone seems to be best.

got this to use with cyclemeter

10 years ago

works great. however, you do need to get it snug and then tighten one more notch. However, It's really not noticeable during the ride. a bit on sizing. if you order online to where you can't try it on first. the sm/m is for woman's wrist and the large is for men's. How I use it. I connect it with Bluetooth to my iphone using cyclemeter. while it is connected I'm also listening to Pandora through my bluetooth headset and there have been no problems at all.

Erratic signal renders useless

10 years ago

I have had a hard time making chest straps work for more than a few months at a time so thought I would give this a try. I initiated and charged and followed all the directions. Tried it on the inside of my arm, the outside, strap tight and not so tight. Tried it higher up on the forearm, down at the wrist and could not keep consistent signal going to the Garmin computer 10 inches away while on my bicycle. It would regain contact and then stop sending if I made even the slightest change in position. It is a cool idea but realistically instead of giving me valuable data to improve my workouts, it completely distracted me and disrupted my workout to the point of returning the device. Maybe a bit more development time would have paid off, I question whether this has even been tested in an exercise environment. I give one star: it did not do what it was designed to do.
