The battery & tool:
The tool makes a good impression (if you keep the low price in mind) and is definitely well used for battery replacement. It's even magnetic, which is at the tiny screws beneficial. So here, everything was perfect.
After the battery was installed, I naturally wanted to check with iBackupBot whether that is really new. First look at the Cycle Count: 0. Very good! However, the capacity figures were not available. It is the maximum state of charge (100) and the current state of charge (91) has only been shown. While I was wondering about the iPhone already rebooted as if by magic. And from there it started newly in 3-minute intervals! The new battery was therefore not usable. Supposedly could remedy a software update. Although I was skeptical, but try making kluch. Unfortunately Apple recognizes the battery replacement, so it is not possible to update must be carried out with the replacement battery (error 29). So I have no choice, as the old battery installed again.
Conclusion:
Delivery: 2 stars. With a week delivery time as Prime product definitely too long. But the customer service from Amazon was very good. Quick and customer friendly!
Tool: 5 stars. Definitely enough for the battery change, several times usable. Schön: Magnetic.
Battery: 1 Star. Since the slideshow is only the lowest possible rating here. Overall there only 1 star because the product is worthless.
