good quality hardware, very bad software implement
The watch itself feels very solid and well built. The ratio quality/price it's pretty decent but the goods end here.<br>There is a problem with the HR sensor, as soon as you move the arm you can have spikes of 30-40 BPM...it's basically useless during sport activities. <br>The GPS at time can be very slow in connecting with the satellites (all metal chassis does not help with reception)<br>Another minus point that just made the watch useless to me is the fact that you can't run the timer nor the stopwatch in the background.... basically once you start your timer/stopwatch you can't do anything else.<br>I was looking forward to this watch but it has been quite the delusion.<br><br>Also worth noting: this has been the second T4, replaced under warranty because the first just bricked itself after few days of usage.<br>Luckily EldarStore staff has been very helpful.
