Amazfit was foiunded just 6 short years ago. and over the last couple years what I have seen about their products is the following.
1. their products are inexpensive but not cheaply made
2 . for those people who do not have the money for an apple or wear os watch they are a good alternative
3. they have a lot better battery life than the apple watch. the apple watch having a 1 to 2 day battery life.. and amazfits watches start at a 9 day battery life.
4. on amazon, the first 16 listings of amazfit watches have a community rating of between 4 and 4.5 stars.
I think Amazfit as a brand have proven themselves to be quite good. I look forward to see them prove themselves even more in the future
