First I will start with what I liked about this. Overall design is good. The build quality is nice, the band doesn’t irritate and it tracks sleep during daytime also.
Now what I don’t like about this product. The battery life is pathetic( only 3 days) . It doesn’t tell about the sleep quality, like how much was deep sleep. Another problem is if you’re sitting idle it will many time count it as sleep( ya u can delete that afterwards BUT it should not work like that) . It doesn’t connect very easily. And the most important it’s way more EXPENSIVE than it should be.
