## Customer Reviews

### ⭐⭐⭐⭐⭐ Fitted perfectly and working well
*by J***Y on 18 August 2025*

Mother-in-law’s ipad battery had failed - it had expanded and pushed the screen out of the frame. This battery was a perfect replacement and has been working without and problems for nine months now.

### ⭐ Poorly manufactured.
*by W***L on 9 September 2024*

The battery connector cable is too long, meaning that once the battery is positioned correctly and the connector is installed, there isn't enough room for the part of the cable running parallel to the battery to sit snugly alongside it, resulting in it either needing to be bent or left to protrude upwards. I followed the instructions to the T, but the battery does not function after the process of trying to manipulate it into a position where I could then close up the phone again. Now left with a non-working battery, and my old battery which is terrible and is now too misshapen to use again. I don't know how they managed to screw up one of the most critical components. Absolute trash.

### ⭐⭐⭐⭐⭐ Good quality and easy to do
*by R***P on 15 July 2025*

Easier to do than I expected. All of the tools are in the pack and I just watched a YouTube video and then followed the instructions. The screws are tiny so make sure you have somewhere to keep them whilst doing the job. The battery itself was already partially charged and went to full charge easily and quickly. A great product well made and supplied
