Product images used to pop in awkwardly and cause the page to jump around, that stopped after I started using this. It mostly runs quietly in the background which I appreciate. Two things id change though, I want a clearer report showing what got optimized, and an option to exclude certain pages from the process.

The preloading thing they do makes clicking between pages feel almost instant. i checked my speed scores before and after and the difference was real not just a tiny bump. solid little tool

Im not super techy so I was nervous about installing somthing like this but it turned out fine. The mobile perfomance is way better and my product pages dont hang anymore when there are lots of scripts running. Honestly the best part is I didnt need to hire a developer to get it working. If I had one wish itd be more granular controls for advanced users who want to tweak things.

Pages just open quicker than they used to, customers have even mentioned it. Not much else to say, it does the job it promised and I havent had any issues.
