Hyperspeed EXTREME Page Speed

Terrific! I had a slight problem with the app when it first installed, in the theme preview (it does not publish automatically), a couple of my pages did not load correctly. I reached out to the theme who fixed it within a couple hours, and my store is now lightning fast! Would highly recommend.

Early days, but the performance gains are looking very promising. Support has been exceptional, and the app itself makes what seems like a pretty daunting set of tasks to undertake very straightforward, with excellent options to pick and choose exactly which optimisations are right for your site.

Installed the app, support was on it, when an issue arrived. There is a fail safe test prior to publishing, which I really like.

Did not use the app a lot, but I can say that the support was fast and comprehensive. For that, I give you a 4 stars. Cheers

Not a good app. This app never improved my page speed. I am getting the same score before and after installing this app.

It does not fulfill all of its promises. I'm still fighting with Java scripts and Contentful Paint. I think this problem should be fixed by Google, but they won't.

Instant improvement, great support.. We'll see how we get on going forward. On our site www.annalise.co.uk

DO NOT USE THIS APP. I installed this app on my site, checked my speed scores. It helped a little bit but THANK GOD this morning I received a call from a potential customer saying my "Buy it Now" button was broke. Luckily I have a really good developer that installed a premium theme and fixed it. It was traced back to this app. I'm spending $500 a day in ads and luckily I uninstalled this app late last night and so only wasted about $100 in ad spend,

It wreaked havoc in our store. The "optimization" process reset the images so we lost a third of our products in the Google Shopping feed which ended up causing problems with all our Ad campaigns. Of course, they are blaming Shopify for this issue but coincidentally, it only happened after installing this app. If that wasn't enough, while the app was installed, several customers complained that the site was down and it ended up costing us thousands of dollars in sales. We are still dealing with the consequences.
Needless to say, try this at your own peril.

Via Googles PageSpeed Insightes, my page score started off at 27. This is low. This is why I was looking for something to help speed up my page. The first time I ran it my score dropped to 23. I ran it again thinking I did something wrong. When I retested my score dropped to 17. I'm not sure how it can do the opposite of what it was supposed to do.
