I'd hoped for a less frustrating cache experience, but got a broken plugin that won't update, frequent 'URGENT! Do this now because the plugin is totally broken!' emails from the developer, and I'm very frustrated because he just offered a refund to a user in the forum, and I responded that he remembered me from the dozen or so back and forth emails in which he did his best - but failed - to get the plugin to do anything other than breaking my WP install. So I said 'hey, I wouldn't mind a refund, since I'm now terrified of ever having this thing on my WP again,' and no response. Not even an attempt to fix it, just no reply - so don't expect support for your 10 bucks, priority or otherwise. Incredibly disappointing.
