Review: Good packaging and Nice quality - It came with 0% battery and I was trying to turn it on.watch itself never shows the battery is down. And I connected the charger still display is off. I thought it’s damaged. After around 3 minutes display shows 0%. Once I charge it full. It’s working perfectly If anyone got product same like I received. Just try to charger and wait 5 minutes, maybe it’s not damaged

### ⭐⭐⭐⭐ Excellent Quality
*by M***. on 24 May 2021*

High quality product. Looks and feels premium. However I have used the Samsung Galaxy Watch 1. The same watch faces that are customisable on Watch 1 are not customisable in Watch 3. So maybe that needs to be worked on in the next update.
