Super part. Steps are very well recorded. Sleep Testing radioed well. Battery lasts sehrrrrr long. Have just 61% (46Tage). Alarm goes well. The silicone bracelet is very skin-friendly. Have it here ordered from a dealer. Package was there in 2 business days. I would advise you all sets 5 more on it and ordered directly in Germany. Instead 7-21Tage to wait.
