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.

I am surprised to read bad reviews. They are doing pretty good job making a speed of my store in a good range and I have got support very quickly.
Thank you !

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.

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!

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.

Terrible support, due to no support, removed the app and it left code in the site that broke features in my store. Had Shopify support involved with the issue and they responded several days later "we refunded the customer" leaving no regard to get the code removed from my website.

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

I have attempted to contact support repeatedly via both chat and email for several days, with no response. This level of disregard for customers is unacceptable, especially for an app that handles crucial aspects of an online store.

While the app may have potential, the complete lack of support makes it unreliable for professional use. I would advise developers to drastically improve their customer service if they want to be taken seriously in the Shopify market.

Unless you are willing to troubleshoot every issue yourself, I suggest looking for alternatives with more responsive customer support.

Altdaten im Quellcode nach löschen der App. Das führte zu verschiedenen Shop Fehler. Es wurde unteranderem kein Favicon mehr angezeigt und andere Apps wurde im Hintergrund blockiert (z.b. Klaviyo). Damit ist man praktisch gezwungen, die App dauerhaft zu nutzen, weil es sonst zu Problemen im Shop kommt.
