The Adidas smart run watch has been the worst purchase I made this year and in my opinion should be recalled. A friend and i bought one each for the Cape Town Two Oceans marathon in April 2014. It was the most expensive one on offer and we got teased to no end by all the other members of our running club who bought competing products at half the price but I was attracted by what looked like really exciting features advertised, especially the pace and heart rate measurements. The device worked on race day but since then its been a complete disaster with one issue after the other.
First of all it never locates GPS signal quickly. I have completed numerous 10-20km training sessions with the device still looking for the GPS signal. Secondly, the heart rate monitor stopped registering my heartbeat after a few months and so i switched that feature off and continued using GPS when it would work occasionally. Then finally a week ago, the device stopped working full stop. It autopaused 1km into my 16km run and did not resume the workout when i continued running nor does it charge anymore. My friend who i bought it with has exactly the same issue.
We took it up with micoach support asking them to help fix or replace the product and they are honestly the most unhelpful support group in the history of customer service. They refused to honour a credit card statement showing proof of purchase and one week later they still refuse to do anything to be helpful. I went into an Adidas store to complain and even though the staff in the store said they have so many returns for this product, the manager was equally unhelpful and couldnt do anything. In summary, if you want to buy this product, don’t. Rather poke yourself in the eye with a long stick, its less painful.

I really love this watch. I have been using it since January 2014 now. The features are incredible. Those expecting great battery life have to get their expectations in order. This is a watch with GPS, blutooth, music, and HRM. That’s going to chew a lot of battery life if you are running all of them, which I do. Fortunately the firmware updates have helped. There’s a marathon mode that apparently will allow you to finish a full marathon ~ 5 hours or so by scaling back on some of the GPS logging or something. I’m only up to about 4-5 miles so that isn’t an issue for me yet.

I know many have reported GPS issues. I haven’t had any but I only just started using the GPS and so far it has been great. Reports are that the many firmware updates and finally addressed the GPS issues so hopefully I won’t have any troubles. I run at an indoor track in the winter and use the speedcell device to track my distance and what not.

I’m a stats junkie so I love the data feedback this watch gives you. I like to run with as little as possible and this allowed me to eliminate my mp3 player that I was carrying. I recommend it; just know it’s shortfalls in regards to battery life.

If you want the most fully featured fitness watch on the market, this has to be it. Unfortunately, if you want accurate GPS tracking, this unit may not be for you.
I am amazed that Adidas have put so many useful features into one sports watch. The heart rate monitor is incredibly accurate (I have tested it against my Tomtom Runner and the readings are always within a couple of beats of each other). The music player is excellent. The training features are extremely useful. The GPS is always a little erratic. My main pros and cons:

Pro’s:
* Music while you exercise
* Good bluetooth connectivity with wireless headphones
* Great screen
* Coloured heart rate zones allow you to see at a glance if you are in your zone
* Fitness test allows you to refine your personal zones
* Heart rate monitor is exceptional and not wearing a chest strap is great

Cons:
* GPS is always 2-3% incorrect. How do I know it is wrong? If you run the same track every day and get a different result each time, that is a little suspicious. So is the graphical track that shows you running through solid items such as houses etc. This is not wildly inaccurate, but it has taken Adidas far too long to address this issue. It may never be as good as it should, which is a shame given the premium price tag
* Heart rate monitor is great, but you need to remember to wear it a little higher than normal above you wrist. If you sweat and then the sweat dries during a rest period, it is useful to give the back of the watch and your arm a quick wipe to ensure heart rate tracking is correct. Dried sweat seems to affect it, whereas I can sweat through a long workout and not have one HRM glitch. This is a minor issue that is easily addressed
