I was really skeptical at first. But I can not really recommend both devices. Who wants to interest a little bit of his body and see the impact of eating habits and sports habits in realistic figures
should be sure to purchase a device. There may be other good devices, but I can recommend this company from Erfahring.
I do not know exactly to what extent (the hospital) measure all these appliances to the hundredth exactly, but I can see a slight improvement in both fat levels after 10 days of extreme sports activities. That's really interesting how quickly responds but the body.
