PageSpeed & Image Optimizer

Flash speed is great. Their support helped me out quickly to solve some issues I had in the beginning.

My speed score went from 45 to 90+. Especially the image optimization is helpful.

"I'm extremely frustrated with Flash Speed Optimizer. As a paid subscriber, I expected my store to be fully optimized, but there's still a 30% unoptimized score on mobile. This is a serious issue since most of my visitors come from mobile, and it's directly impacting my business negatively. Despite multiple emails and chat messages, I've received zero response. This level of neglect is unacceptable. I demand immediate action to optimize my store and compensation for the damage done to my business due to their inaction. Do not trust this app if you value your business!"

It simply make all your images to fake board at the first loading, then make lazy loading to img, BUT in may cases java have failing and images not show up. page speed goes up immediately but it totally ruin the view overall. second thig: it makes 1K back links from one IP.
And support is not answering at all.

Terrible support, due to no support, removed the app and it left code in the site that broke features in my store. Had Shopify support involved with the issue and they responded several days later "we refunded the customer" leaving no regard to get the code removed from my website.

Saw this on Youtube and it helped me to increase my pagespeed score

I never write a review, usually only if I´m disappointed.
This time it is different.
I´m super happy. The app works perfectly for me. from page speed 37 to 95 (I have screenshots to prove it).
For me it´s a investment and 20 bucks is not cheap, but I rather pay more for something that really works.
The only part I dont use is the picture compressor.

Last Thing I really appreciate: no begging for reviews, no upsells. Just the app.

Perfect.

It works as described in the video. Simply setup and easy to use.

This developer doesn't respond to questions on slack or email. I need technical help and I have questions about usage fees. I've had the app for a little over a week now and my website speed hasn't improved. I will be cancelling this subscription before I'm hit with more usage fees.

It does nothing for my store. I canceling before the free trail is up.
