About - Mio Alpha

The Mio Alpha is part of the heart-rate monitor test program at Consumer Reports. In our lab tests, heart-rate monitor models like the Alpha are rated on multiple criteria, such as those listed below.

Indicates whether the model employs a chest strap mounted sensor that transmitts to a watch, a chest strap mounted sensor that transmits to an iPhone app, a watch that requires the user to touch the rim or button to take an intermittent reading or a watch that takes continuous heart rates from the user's wrist.

Accuracy was measured against a highly accurate electrocardiograph; the higher the accuracy score, the more often the monitor displayed the same heart rate as the reference did.

Best Uses
Fast Walking
I read the CR evaluation before purchasing this monitor, and was impressed enough to purchase this product. I have an iPhone with an exercise app which tracks all my pertinent information including course, times, inclination, etc. This product pairs with and works flawlessly with it. <br />Buyer Beware - If you run or fast walk this device is spot on accurate 99% of the time, I think that is because it is optimized to work best when your forearm is bent or held somewhat parallel to the ground as in running or fast walking. If the arm is held down as in normal walking/hiking or slightly bent as in biking the reading is way off rendering the device useless. The company should provide additional algorithms for walking and biking which would account for the difference in blood flow when the arm is not parallel. If you wear it for walking or hiking and keep your forearm bent it will work excellently but that is awkward when you hike for hours on end. You must also be careful not to wear the band too tight around your wrist for a long period of time. It really doesn't have to be worn very tight anyway so test it yourself for comfort and function.<br /><br />I don't make much use of the max, min, and in-zone features because the app on my phones captures that information and displays it in a far better format.<br />There is no history function either on the monitor which will be an issue if you don't use a phone app with the monitor. <br />Please keep in mind that if you use a phone app the phone must be with you when you wear the monitor. You can't save the data and download it later.

Works, but does it have to be so pricey?
Easy to use
Links With Several Apps
Hard to read in low light
Best Uses
Cardio exercise
I use this for cardio training on an elliptical machine and for circuit training. It works better on the elliptical than circuit training. For example, it doesn't give an accurate reading when doing push-ups because your hand is bent at the wrist. It picks up the heart rate pretty quickly and has better range to connect to iphone than it says it should. It seems too expensive for what it does. On its own, it can only track heart rate and time. Mandatory to link to something else to analyze any information. Backlight would be nice, but I'm sure it would be a battery drain.
How long have you owned it:
A month or less
Bottom Line
Yes, I would recommend this to a friend.

Great for Cycling Team with Wahoo App
Very long battery life
Best Uses
Very rewarding to see how many calories consumed while biking, team up with Wahoo Blue SC and you have cadence, heart rate, speed, and GPS without a chest strap on your iPhone or Android. The future is here.
