Thunder Page Speed Optimizer

customer support behave is very good

Absolutely fantastic app, was having trouble with the speed of my Shopify store (https://countywear.store), but this app done an incredible job of highlighting the issues and resolving them for me. A+

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!

It was really good! the speed of my store got improved and the support team service is good! highly recommended

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

This app gave great results from my homepage, raising the score from 47 to 77.

I had a few doubts, But the Dev, George, gave me great advice on what I should be doing.

Was all very simple in the end.

Thanks George

This app is very fantastic... Highly Recommend... If you want instant results install this app right now... 100% guaranteed results.

I can’t open the operation page all the time, and there is no reply to the email contact. There is no reply after contacting for three times in a row. Extremely bad service

Great app! It made my shop fast and the service is amazing !

Upon first install the app worked as expected. The past 48 hours the app has glitched and when opened in Shopify it presents a white/blank screen with no further instructions/links or error codes. I reached out both times with no response back. I uninstalled and reinstalled the app thinking a crucial update was missed; however there was no change. App was uninstalled permanently and other venues have been sought out.
