Mio ALPHA 2 is rated 3.9 out of 5 by 51.

Rated 5 out of 5 by scottoftheforest 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 5 out of 5 by Cocoa from This is a great single-purpose watch.Very accurate I got this a couple of years back. It still holds a charge forever and it's very accurate.I don't run with a phone(I hate that) and this also works in the pool.At $110 bucks now it's a nice assistant for bikers and runners who do not want those clunky strap-ons. Could use a UI enhancement where you can track interval time AND HR. Or be able to choose chrono mode vs. HR+Time. Easy to read numbers-great font choice. Could use an LED light somehow

Rated 4 out of 5 by twalks 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 derekm2j 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 iris19 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 Thx1138 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 4 out of 5 by DRUNNER from Excellent Hardware, Poor MIO GO Application. I bought a Mio Alpha 2 three weeks ago, I am a 5K/ Half Marathon runner, Heart rate Accuracy is great.The BAD: Impossible to get the time per Lap(or time per Mile, Interval or equivalent name). To MIOGLOBAL people: The watch is registering that Info and YOU CAN NOT SEE IT. Not in the Watch, Not in the MIOGO Application (for Android GalaxyS7), Neither in the CSV file exported from the MIOGO Application.The Time per LAP is a great feature, it is an EXACT number registered by the Watch.it is not like steps, calories and distance which are close to the real numbers PLEASE GIVE US A CHANCE TO SEE AND USE THAT TIME PER LAP FEATURE.

Rated 4 out of 5 by Pablo from Magnificent HW, poor SW. The gadget is great! Work perfect for biking and swimming, I owned a Link also, but decided to move to Alpha just for tracking my swim training.The sw is poor. No way to manage info outside the phone. I don´t know if it is my MotoG but the BT connection is very unstable and hard is to finish a training session all monitored (another reason to move to Alpha with built in memory).I also have had trouble working with the PAI sw.I hope both sw would improve in the future to be up to the HW´s level.By the way, I ask for a future firmware update to have a setting to set off the blinking lead. Is very annoying at night or in the theater. Thanks. Pablo
