Product review (3 stars): Did the job, but broke during the first use
The tool worked perfectly for the outer spring, but the eyelets on the inner spring weren't quite large enough for the tool to fit easily. We managed to get it after a few tries, and this tool definitely made the job easier.
However, while we were using it during this very first use, the inner spring broke! Thankfully that inner spring isn't necessary for the tool to work, but for such an expensive piece, I was very disappointed that it broke the first time I used it.
