I ordered a igotu Qband HR from New Zealand and when I printer the invoice noticed there was No Country field in the Address. I Emailed them they corrected it and 2 weeks later (I paid for surface) I had it working with my Huawei P10 Lite.
The igotu Qband HR Smart Fitness and Heard monitor was a brand I knew nothing of but the reports were encouraging. It turns out to be comfortable to wear has a great battery life (about a week if you don't monitor your heart full on) and the program that works out the information is first class. I like that is silent and the phone remains silent. Texts vibrate the band and appear on the display. It shows elevations. Check out you heart beat on your phone afterwards at any step around the path.
Would be great if the igotu Qband HR was waterproof and the strap had a band to stop the strap end from moving round. That would make it easier to do up when putting on and stop it dropping off when you catch it on something (like reaching into a cupboard)
