Unpacking:
Positive unpacking I noticed immediately that iMaze mitliefert a German manual. You need not necessarily good to know that such a thing is. In addition to the instructions found in the package, of course, the chest strap and the transmitter unit. The chest strap is connected via two pushbuttons with the transmitter unit. A battery is already in the station and can be easily replaced. The capacity of the battery, I can not say anything but my chest belt to function for a few weeks with no problems.
Functionality:
With the included user manual is coupled with no problem. But you should (also available in the manual) before the first attempt to close all apps and turn off the iPhone and then back on again. Maybe it can be done without but that I did not try. After the first couple, the chest strap connects to the Create namely automatically with the app. I use runtastic and have also briefly looked at the iMaze App. The iMaze App is okay but runtastic is much better. But the cost nix iMaze App. That there is a paid version as posted here short time, is to me not noticed. I missed no function.
If runtastic the belt without problems works. Simply connect via the settings and there you go. The heart rate is recorded without gaps. I am not a doctor but I think the measurement is very accurate. I had no kind of strange rashes that occurred to me. Also, the interval training works with the Herzgurt very good. The chest strap does so what he should and that. Without dongle or additional software For 5 star.
Ergonomics:
The fit of the belt can be easily adapted to the chest. Allegedly, the belt is even waterproof but that I have not tried. If it is set correctly, then tweaks and presses me nothing. It was different with my old Wahoo chest.
Compatibility:
The evaluations will be complained that not stated that only the iPhone's more, no Android phones. That I can not understand, unfortunately, because in the right detailed description everything is recorded accurately. I have tried it as I said with the iPhone. There will be also with some Nokia phones and Blackberry phones. The until now no app exists, in my opinion is not the fault of iMaze. Incidentally, I read last week some news that Google is working on Android and on the support of Bluetooth 4.0. Then this belt might be compatible with other phones.
Conclusion:
Anyone looking for a reliable chest strap, which works beautifully with the iPhone, which is right here.
