Product review (4 stars): Great tool, but probably could have gotten by without it
Great tool, took 5 seconds to use it and it did the job on the outer spring.  I tried to use it on the inner spring as well, but it wasn't quite made for that, there is a separate tool.  In hindsight, since I used strength and pliers for the tough inner spring, I probably could have done the same for the outer spring and not purchased this tool.  It's insanely expensive and will end up on ebay soon.
