Customer support is the worst. I have been trying to reach out to customer support for the past two months, but there has been no response. I have never experienced this kind of careless support from any app. I am facing cache issues, some functions are not working on some devices, and some features are visible on some devices but not on others.

Scammy and Unreliable – Avoid at All Costs! Charged my account after I uninstalled and I have tried to send messages to get help with fixing and no help and it's almost been a week. It's messing up my shopify website and other billing subscriptions. Do not download and install!!!!! Save yourself the trouble and find another app. You deserve better than shady billing practices and ignored support requests.

Company will not reply to any messages or emails. Update: Only after I left 1-star review, the company did respond with a brief message that didn't clearly answer my question, and then asked me to change my review, but has not replied to my follow up question. I am now trying to use the compress images feature, but an error pops up that I can't read. I believe it wants to ask for more money. As others have said, I also discovered this app is charging me usage charges which are not disclosed anywhere. Update #2: I changed the review from 1 to 3 stars. Someone from the app replied to me and pointed out where the additional usage charges are displayed. I don't recall ever seeing this before, but it is there now. The app did improve the speed of my store, but the extra usage charges, bugs with compressing more than 1,000 images, and limited customer service mean it's not a 5-star app.

I’m not going to give them a 1-star as some did because that seems petty. The app seems to work, although I’ve been trusting their analytics to tell me that. My concern is that they have "usage charges," but I have no idea what they’re for. I searched both the FAQ and documentation for "usage," but got nothing. I sent an email asking, but never got a response. I see a number of other reviews that mention this too and, for the record, I’ve checked my junk mail folders. Because of this and the general need to cut back on paid apps, I’m uninstalling

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.

I installed this app to help me increase my website's speed, because I was unable to edit my code and remove the scripts myself. After this app helped me increase my speed 30-40 points, all of the sudden it stopped doing that. When I contacted the developer, they were not prompt in responding and only said I had to keep checking my speed. Compared to all apps I use, the customer support was by far the worst considering how expensive the app is!

Very expensive and misleading, money pit. It does what they say, but at an unreasonable and unexpected price, way above $19.90 they advertise. Also, they raised their base prices without warning, when I installed, the base price was $9.90

Unable to reach anyone. App not working. The comparison page speed does not load at all. Tried emailing 3 times no response. Also if you have something like Pagefly, it will cause issues.
