Rocket Page Speed Optimizer

Kinda works, but its highly inflexible (breaks other apps with no way of whitelisting them), the implementation is very weird, it updates your theme daily (or more) to change an expiry date. If this date is reached it wont work anymore, as a way to break it when you uninstall it. Generally this works completely without a server, so a one-time payment would make more sense.

I've been using this app for years, and it has improved my CWV scores. The customer service has been responsive and helpful as well.

Non migliora niente ! Solo perdita di soldi !

I have been using this for 5 months. The concept is great, but the implementation of this is trickier than meets the eye. There are plenty of issues with the implementation and support side.

Even if the app doesn't work, they still charged me. The first answer was a recommendation to just uninstall the app, which say a lot about their ethics.

Great app, it actually changed the scores on pagespeed. Love the instant page load feature.
