Mio ALPHA 2 is rated 4.093023255813954 out of 5 by 43.
Rated 5 out of 5 by from Fantastic device I'm a relatively young heart attack survivor, and intend to stay that way. I've been waiting for a wrist worn device that seamlessly connects to my phone for road cycling and hiking, and this Bluetooth unit fits the bill.Initially there wereally issues connecting with my fitness apps of choice, Runtastic, but Runtastic soon updated their apps to include the Alpha 2. The watch is comfy and stylish enough that it is my day to day watch too, and waterproof, which is a great feature.Holds a charge for many days too. Don't need a smart watch to read emails and texts. Need an accurate, well built device with excellent support and overnight delivery to my door at an affordable price.Home run Alpha 2.

Rated 4 out of 5 by from I like it so far but... I just purchased a Mio Alpha 2. I have used it for three workouts so far. What I do like: the strapless heart rate monitor. What I don't like: how hard it is to start the workout cycle with the buttons. Each time I have to start over from the beginning because the timer won't start. Instead of the timer starting, the watch "ends" the heart rate monitoring. That is very frustrating. Plus the clasp at the end, doesn't stay put. Today, the black plastic part came completely out of its spot on the watch leaving the strap flapping. There has to be a better design to keep the watch snugly on the arm.

Rated 5 out of 5 by from Mio Alpha 2 everything I had hoped I was an early adopter of the mio alpha, in fact I followed the device from the days of kiss starter. As a guy in the medical profession I am familiar with the technology and saw real promise in the product. All the things I wish were present in the alpha are there in the alpha 2 i.e. accelerometer, distance, kcal. I love the accuracy of the device and have been relying on it for my crossfire style workOuts. The one thing I wish it could do would be to function as an activity tracker as well. Oh well, I guess I will pickup the FUSE as well . ALL in all great product and great company.

Rated 5 out of 5 by from the very best heart rate monitor i ever owned! i got this 4 months ago and i keep being amazed on how much resistanse to baniging, water, and sweat resistancee it has, it does have a few seconds delay when training at 90-100% the heart rate comes up 3-4 seconds later, not inmediately, but its so accurate and with the app on the phone i can make all kind of calculations and adjustments to my training, the watch itself its very comfy not bulky, i really love it, i even started giving them as birthdays gift to my friends lol even of they dont work out, as motivation so they do...

Rated 4 out of 5 by from Need some more features, anyway great product I've been using this product for 4 months and I can say it's a great product. I love the design, the comfort and the big clear display. Also the fact it can work in the water was a main reason I preferred over other products. Anyway, I would suggest a few things: first, to give the option for a small version also for male: I have a small wrist and the large version is a bit too large, also the strap has a poor lock system which tend to open during training sessions. I would add some more feature, as: a clock alarm, useful when we bring the clock in vacation; the possibility to keep the light always ON, during night training sessions.

Rated 2 out of 5 by from Great gear but unfortunately poor software The hardware is really great. but. It is the poorest app I've seen, and no website to log on to see your performance.Trying to synthesis why I struggled so much:The Mio Go app does not allow you to store your data in the cloud or access it from the web, all is stored in your cell phone and if anything happens, or you change your phone, all is lost. There is no option to upload data stored in the watch to another 3rd party app like Garmin or Suunto and others do...Because of this, you need to use a third party app, meaning you need to get your phone with you during the workout, which is exactly what I wanted to avoid when purchasing the Mio Alpha 2. The Mio Go App does not offer GPS tracking neither... Third party apps like runkeeper, runtastic, endomondo etc... will work only if you have your phone with you at the time of the workout, and you have to go with pro versions which means monthly subscriptions if you want to connect your HR monitor !!!I consider that when you have already paid a significant amount for the device you expect to have some minimum basic features without need to pay for extra stuff.I really do hope Mio people realise this, as i am not the first one to put some comments like this, but I really wonder what they are waiting for, and when a serious application and associated website will be released so that we can really enjoy the product.

Rated 4 out of 5 by from Great watch for heart rate monitoring I am using this watch for dailly monitoring of my heart rate as I go about my activities, during exercise classes and walking.It's easy to use and the big screen makes reading easy so one can pick up speed or cool off. Best of all, I don't need to use a chest strap!
Date published: 2015-02-07
Rated 4 out of 5 by from has all I need Tried the watch a few times already and it is easy to use. It is an improvement from the 1st watch we purchased. My only negative and it is not a show stopper is that the light is really weak. Barely can see it in darker situation. Also you have to tap harder on it to get the data with light. Not good when cycling and keeping both hands on bar. Would be a 5* otherwise
