- Ebay seller samsonescu (206) currently sells three Dreem headbands (Dreem, Dreem 1 & Dreem 2) on ebay. samsonescu (206) writes about the accuracy of the Dreem headband:
“Please take in consideration that device is a FDA medical device class II and has almost the same level of accuracy of a medical polisomnograph (87 %) which costs 15 to 20 times more.”
- We asked samsonescu (206):
“You have three offers on ebay, a Dreem, a Dreem1 and a Dreem2 headband. What is the difference between these devices? You write the accuracy is 87% of a medical polisomnograph . Do all three devices you sell have the same accuracy?
Accuracy values samsonescu (206) gave us on ebay:
| Headband | Accuracy | Deviation | Source |
| Dreem 1 | 87.00% | +/-3% | Ebay seller samsonescu (206) |
| Dreem 2 | 92.00% | Ebay seller samsonescu (206) |
- Samsonescu (206): “Check the studies on Google search”
