This is a must have app, even if you aren't going to purchase any of the fixes through the developer. Support is awesome, seriously. I was very surprised how quick the response time was--it was always within 24 hours, often well within 24 hours. I actually paid for the premium speed fix for a little less than $400, but it was well worth it. There were a few things that didn't properly work on my site afterwards, and I was like crap they ruined my site! Thankfully, they fixed everything within 24 hours, even as I discovered a couple more errors afterwards. Now my site runs faster and works as it should =) Very satisfied customer.
