Very Helpful app it really increase the speed and the Customer support is also very good and excellent Help a lot . Thanks George....

Amazing app. Am the designer / owner of ourhatsdeservebetter.com I was stuck with poor performance linked to technical issues I could not deal with. 18% overall improvement on my pages, home, collections, products, ..., measured on PageSpeed Insights and lighthouse, both on mobile and desktop view, without impact on site visual quality. So easy to use that I just run it without the need to require technical support. And it is FREE!... I don't understand the business model but I love it!

Just very Good! The use of the App was just fantastic and really easy to use. It made my site way much better on Mobile (desktop was also better). The Support answers all Questions and is very acceptable and dosent hesitate for anything.

Definitely over a 4.5 Star Review!

Probably one of the best app if you're looking to speed up your shopify theme, it helped us increase our score by 21 points!

The apps works great and George has been so helpful with installing and improving the app on our website!

Incredible! If I were reading my review sincerely, I wouldn't believe it, because the result of the app is ABSURDLY WONDERFUL, not only the app but also the support. My page speed almost tripled in GTMetrix and PageSpeed, it went from 35 to over 80 performance. I spent more than 2 hours being attended by Georgi, even though my plan was still free, simply surreal. Avada? Booster? No, no my friend, Thunder Page Speed Optimizer, this app will solve ALL your problems, honestly it's unbelievable, when you install it you'll realize that too.

wow, how is this free. Increased my sites speed with multiple seconds. I highly recommend this app to anyone its amazing
