Nice but…

Could have been nice, I can see the more aggressive approach to caching having its benefits. There are also drawbacks, most of all a higher probability of crashing a site. Have had 4 crashes related to SPL on maybe 35 sites, compared to 0 for WP Fastest Cache on the same amount of sites. That number is too high for me, hence the 2 stars.

I do like the interface and the level of finetuning, and I think performance on sites using SPL was a little better than sites running WPFC.

Support was a bit too lazy (‘we didn’t do it’), might be you need PRO to have good support.
