Product review (4 stars): Expensive, but necessary
Yeah, it's an expensive tool, definitely more expensive than it should be. I almost didn't buy it. In hindsight, I'm glad I did. Replacing the two springs took about a minute for each, and given the lack of elasticity in the spring, it would have been a major pain to do the job without this tool. My recommendation: Buy the tool, use it for the repair, then sell it on eBay or craigslist if you don't think you'll use it again.
