App seemed to be doing a great job, then about 2-4 weeks ago the page speed dropped. I've tried three times to contact support, but no one has gotten back to me.

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.

Scam app. Charges extra with no clear understanding why.

Worst customer service I have ever experienced. I have been reaching out trying to get help with numerous things since I started using the app and I have never received a response.

I think no one is working on this. I was interested in purchasing the paid plan, but for 4 business days I received 0 support.

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.

The app has been incredibly helpful for me. Marc was really supportive, and I highly recommend this app to everyone. Every single penny spent is worth it.
