That sums up my experience pretty well. I tried installing it for a couple of sites and seemed really cool at first. But just weird things started to happen with styles and such and it seemed like it was going to take a lot of research and debugging to get everything dialed in. Not really having time to do that, I disabled it and put it on the list for later. I wouldn't call it a "negative" experience necessarily, just not the easy win that I was hoping for.

I do think it would be awesome for some legacy code if it was critical to get the performance tuned up and you have a day or so to get everything configured.
