Geweldige ring voor slaaptracking

[This review was collected as part of a promotion.] Ik draag de Human Air ring nu al ruim 2,5 maand en ben er ontzettend tevreden mee. Vooral het slaapgedeelte is voor mij een echte meerwaarde: ik krijg inzicht in hoe ik slaap en merk dat ik hierdoor bewuster bezig ben met mijn rust. De ring zit comfortabel, ook 's nachts merk ik bijna niet dat ik hem draag. Daarnaast is de app overzichtelijk en gebruiksvriendelijk. Kortom: een aanrader voor iedereen die zijn slaap en gezondheid beter wil monitoren!

Monitoring sleep well and heartbeat rate!

[This review was collected as part of a promotion.] I bought this ring for two months ago. My career is quite stressful and sit for long time. This ring can help me to improve my health by reminding moving, controlling caffeine consumption, and relaxing from stress. It has programs for breathing meditation that interesting. I love this ring.
