My store seems to load faster since I started using CrazyLoad. It was easy to set up, and I barely have to do anything once it's running. Exactly what I was looking for.

As our product catalog grew, site speed started becoming more of an issue, particularly with all the images. This has helped cut down some of that extra weight, and the pages definitely feel faster now. I’d appreciate more detailed reporting about exactly what was optimized. Having more control over which optimizations are enabled or disabled would also be useful.

The fact that most of the image optimization happens in the background is really convenient. I can actually feel the difference when browsing the store, and our speed scores have improved since we started using it.

We have a pretty large catalog with a lot of product images, so keeping the site fast was becoming a bit of a challenge. This has helped by automatically compressing new images and making the pages feel lighter on both desktop and mobile. Our speed test numbers improved too. The dashboard wasn’t completely obvious to me at first, and I had to check one of the settings before making a change, but overall it’s been a solid improvement for the store.

After having this running for a while, the store feels quicker when I move from one page to another. It’s also nice not having to manually go through our images all the time. One less thing on my to-do list.
