Wearable for sleep tracking

[Ichi-Zero]

Hello Fellow LTTers~ 

 

I'm looking to get a wearable for sleep tracking/alarm clock; I see there are many budget options but I'd like some insight on some recommendations.

Please keep in mind my main priority is for accurate sleep tracking, with secondary (nice to have) feature for "light sleep wake". I will be making this purchase in Canada, so please take currency into consideration  

Thanks for reading and have a wonderful Christmas~

 

1) Xiao Mi Band 4    $50 CAD 

2) Galaxy Fit-e         $50 CAD

3) Fitbit Versa Lite    $130 CAD (This is getting a little expensive)

4) Open to the idea of Xiao Mi Band 2/3 but they're largely out of stock and difficulty to find now. 

4) Recommendations please~
