Sigma Sport iD.TRI Triathlon GPS Watch with Multisport Training Mode, Wrist-Based Heart Rate, Outdoor Navigation, Lightweight and Waterproof

I received this about a week ago and I'm really liking it so far. It was quick and easy to set up and sync with sigma on my phone and it's very handy that it vibrates and the smart light flashes when you have a notification. I like the band as its rubber so doesn't dig in to your skin like some other watches do. It has a heart rate detector which is pretty fast at finding your heartbeat when switching to this mode. I like that you can get bronze, silver and gold trophies when meeting certain step counts and this will make it vibrate when you've hit that many steps to show you have a trophy, I find this very motivating. To log a training session is very easy to do also, you don't need to be tech savvy to use this as it's so easy to do with the on screen instructions. Overall I am really enjoying this and it's given me more motivation now that I can see my results after training. Would definitely recommend to anyone thinking of buying one.

I used the product mostly for cycling, road cycling at that. The data it produced for speed and altitude was very good and accurate. Comparing with some of the high priced models avaliable. As for the heart am rate and calories, for me was off. I previously have had experience with Fitbit. The app was easy to use although I did have many connection issues with GPS and connection to load my data for the day (using Android device). Its a basic looking and working watch that does a good job given the price, but ultimately if you are looking for a top end, pro, precise data watch I would spend more....

A little let down with this product, aesthetically it appears dated along with the software & display. I’ve had difficulties in finding a GPS signal in strong signal areas which has been frustrating as my phone meanwhile had perfect signal. Not a terrible piece of kit however I would rather fork out the extra £70 for the Apple Watch Series 3

Having been a long term user of Polar V800 this was a big step to change...I loved the ease of set up, pairing to phone synching with Sigma App. Uploading to Strava was very easy....The built in workouts very good, especially for training in winter. I love the flashing LED "Smart Light" o heart rate zone, Blue, Green, Orange...great when on Turbo or Spin class. Smart notifications and activity tracking all good. Excellent value for money....

I was very exited but what was my surprise when the watch arrived broken and clearly used. The screen protector has being re-installed and the screen was broken. Also, clearly someone used before as the box was damage in the exactly point you will do it when you take out the item. Anyhow, it is a shame

The watch itself is good. Comfortable on the wrist, nice display, clear functions, easy to use. However, the app you download to your iPhone to connect the 2 and analyse your data is not so great. Visually it's rather old fashioned but also just not clear how you use it. Wouldn't recommend based on the app which is a shame because the watch itself is nice!! I also had to wait a few times for the watch to find a GPS signal, this was frustrating, especially when standing outside in the cold wanting to run!

I had trouble linking this with the App. I tried quite a few times and it would not do it. If I couldn't do this it effectively made the tracker unusable so I returned it straightaway. I always believe things like setup should be easier, if it falls at the first hurdle it does not bode well for other features.

The watch is fine but the companion app for android does not work well at all. I had to uninstall it as it was crashing my phone.
