Review: Excellent value, clear instructions, plenty of tools included - Arrived quickly. Tools were sufficient. Instructions were clear. The side buttons sensors were hard to get off, but fortunately, they include a flat razor which did the trick.

### ⭐⭐⭐⭐⭐ Works great for galaxy watch
*by W***E on December 5, 2025*

Worked perfectly for my Galaxy watch 46mm 2019. Only problem was the screw driver point was too sharp and I thought the screws were stripping but it was the point on the screw driver not allowing it to fit in the screws correctly. Other than that. Everything works perfectly and the battery is good.
