Nevertheless, I simply missing some things, other watches in this price range.
Display:
It is not possible to let them eg pulse and elapsed time simultaneously show. You always have to toggle between stopwatch and heart rate display back and forth.
It is gererell impossible to get more than one value on the display.
The stopwatch starts running with the start of the pulse measurement. I do not actually start the heart rate measurement right at the start of the run, but already to control eg the resting heart rate. So you have to start the whole thing twice if you want to have the pure elapsed time.
Very bad, I find that you enter his date of birth and the clock then estimates the maximum pulse, the actual value can not be entered! For me the clock estimates the maximum heart rate at 180, but I have a Maximlapuls of 204. The figures in% of the maximum heart rate you can then forget about. Example: I train mid-paced endurance runs in a pulse range of 80 to 85% of maximum heart rate, which corresponds to the training theory. I then a pulse to the 170. The clock shows but then projected to the estimated value of 95%, which is quite a different training area.
Menu navigation:
I think the menu for confusing and difficult to understand, once you turn the knob to a different menu, sometimes with another, sometimes you start with the A button and stop with button B and in another menu, it is just the opposite. The manual will help here and not really, but more below.
Pulse:
I have the impression that the pulse value is not displayed correctly. So either I have had three very good days in the previous runs or the clock is felt at 5 to 10% less than any other heartbeats previously borne by me watch.
Operating Instructions:
I hold up for obscure or false. It says I can do everything with the A button, etc would be much better with button B to practically oriented to explain, so I will train you how I start the heart rate measurement, as the stopwatch, as I finish the measurements as I delete the values and point to zero.
And above all, some of it is probably (probably from excessive caution) bullshit !!!! Training range 90 to 100% of maximum heart rate = Fatal ???? What a stupid assertion !!!! Then indeed all runners would fall in competitions to 5,000 meters, where you can reach this zone loose after the race dead !!!! Referring then to wrong detected maximum pulse of the clock (see above), I would, because I came to the finish with a pulse of 195 in the last 10,000 meter race, so after this clock with 109% of my maximum heart rate (!!!!) was probably clinically dead.
My impression: Stay away! In this price range there are much better watch!
