Reviews always miss 2 things: durability and company support / reliability and integrity. My Biostrap battery lasted about 9 months and was not able to last long enough to monitor 7 hours of sleep. The company absolutely ignored requests for help and offered to sell me a new one. There are better alternatives from reliable manufacturers.
I recommend - Biostrap.
