On paper there are some potentially incredible deals to be had by ordering unknown brand products direct from China. I was delighted with such a purchase for my daughter at the beginning of the year. This was for a Xiaomi Mi Band HR, the Mark 2 version of the, now famous, Mi Band personal activity tracker. Unfortunately, my daughter managed to lose her Mi Band so now I've done some research and taken a punt on a new and more advanced looking personal fitness band, the SMA-Band smart activity and heart rate tracker. I've ordered one and will post a detailed review when it arrives in around three weeks.
