Withings Go is a budget fitness tracker with an amazing battery life and simple display.
Pro Very easy to read the display in all lighting conditions
The Withings Go fitness tracker uses an E ink screen, the same as what you would find on an e-reader. Rather than being lit like a usual digital screen, it is much more similar to ink on paper. This makes it very easy to read even in very bright conditions or when in the water.
Con Very inaccurate sleep tracker
The Withings Go is not a good option for someone wanting accurate data on their sleep habits.
It often doesn't detect times you wake up at all, or sometimes registers them as "light sleep". Many users have reported the number of hours spent sleeping being consistently off by a couple hours or more.
