## Customer Reviews

### ⭐⭐⭐⭐⭐ Great bit of kit.
*by  on Reviewed in the United Kingdom 5 June 2026*

Love it. Has everything I need as a hobby runner. The battery life is incredible, and the screen is easily viewable even on the sunniest days. Tip: buy screen protectors. I didn’t and now have a scratch which is quite deep- silky me. It is quite chunky. I have slim wrists and it doesn’t bother me, but might some - photo included (Stan says hi). Just wish the app wasn’t so pants.

### ⭐⭐⭐⭐ Good
*by  on Reviewed in the United Kingdom 8 June 2026*

Very good watch. I use it to track my sleep and its useful to track your cycle as a woman. I didnt realise how 'stressed' i was.

### ⭐⭐⭐⭐⭐ much better comparing with old 245
*by  on Reviewed in Singapore 3 April 2025*
