## Customer Reviews

### ⭐⭐⭐⭐⭐ Fine
*by S***R on 4 June 2022*

Works fine.

### ⭐ Poor battery life
*by P***S on 2 October 2024*

Took an hour to fit to my Apple Watch only to find that once fully charged (recycled 3 times) it still struggles to last 6 months. I suspect it is very old stock.

### ⭐⭐⭐⭐ Works fine
*by J***G on 3 January 2025*

No issues so far, not expecting a long term fix but it’s fine
