I use every cardio session, simply attach the transmitter on the chest (and moisten the game with the receivers) put his watch and presto! The transmitter does not interfere, does not slip, it can be adjusted at will.
The watch displays several screens during a meeting: time and duration of the session, your heart rate, calories burned. Personally I leave the screen on the frequency, I adapt my speed and intensity cardio session according to my fc and because of that my sessions last longer because I am weary slower. Small convenience if you can not afford to look at his watch to see the state of his fc: the watch emits a sound when you step out of our comfort zone (and for those who do not want to sound: we can off!)
Once it marks the end of the session, the record appears: the duration of the session, calories burned, average and maximum value of our fc, and the time left in our comfort zone.
In addition, there is a space in the settings "data" division comprises the latest reports of the previous sessions, and nice little touches: a combination of all sessions performed since the beginning (the number of hours, sessions and calories burned )
The material looks solid, for now it only been a month that I have this frequency so I am not too soon to assert completely.
In short, I am thrilled with this purchase that helps and motivates me in my cardio workouts, I recommend it for all those who wish to invest in sport :)
