I have attempted to contact support repeatedly via both chat and email for several days, with no response. This level of disregard for customers is unacceptable, especially for an app that handles crucial aspects of an online store.

While the app may have potential, the complete lack of support makes it unreliable for professional use. I would advise developers to drastically improve their customer service if they want to be taken seriously in the Shopify market.

Unless you are willing to troubleshoot every issue yourself, I suggest looking for alternatives with more responsive customer support.

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.

"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!"

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.

I installed the app for the image optimization as they didn't charge extra for additional image optimizations. But the rest of the functionality is also great and it improved my speed beyond my expectations.

Great app for image optimization & pagespeed results. Could reduce my image sizes by around 60%!

One app that covers speed and image optimization for a reasonable price. No additional fees.

The app has been very helpful. Marc helped me a lot. I must recommend this app to all of you. I wish Marc will be present when I need him.
