I have long been looking for a heart rate monitor, which is suitable for me a beginner. Important to me a correct display of the pulse was uninterrupted and simultaneous display of the time to keep the fitness center eye on the time, and watch the heart rate during training. The Beurer PM25 heart rate monitor is perfect for me (1,71m, 73kg). The bundled with included (!) Chest strap is perfect, without pressing, the clock shows the pulse a few minutes after application to (I prefer both in the locker room, and already have a signal, before I go to the devices). And the chest sensor combines totally straightforward and immediately contact the respective cardio machine. I got no problem with regard to the other exerciser chest sensors, and carry the clock and the belt now for over a month each time (3 times a week, for about 2 hours). I have already recommended to all my friends!
