Booster Page Speed Optimizer

I first thought this looked like a great app and it definitely improved my speed. Unfortunately, it also removed half the content from my home page (and I tried twice turning on and off the app with copies of my theme and the same thing happened).
I tried contacting support but received a note back saying as it was a free app there is only documentation support.
It might be a conflict with something on my site but I would definitely recommend you take a copy of your site just before adding it and check your site carefully after adding.

Did not see any difference

Installed because of great reviews however my store actually performed worse. Google page speed for Desktop dropped from 84 to 66 and Mobile dropped from 45 to 28. It also fails Speedboosters Shopfiy analyzer. Hope support will contact me to understand why the poor results.

My site's theme is a little bloated and I saw this app. The ONLY reason I gave it 2 stars is because their UX is so fun. It was simple and rewarded me with confetti for clicking a button! However, I cannot recommend this product as it actually lowered my site's score on Pingdom (75 to 74) and PageSpeed Insights (33 to 25). From what I can tell, it added .1 seconds to the load time.

I would love to love this product, but cannot. But their development team has done a great job with the UI so while I cannot justify using the app I genuinely enjoyed it for the brief time that I did.

I should also add, their response to this issue (slowing page load speed) is boilerplate and does not address the issue. If "page speed apps such as pingdom or gtmetrix will not show any improvements when the app is installed" then how do you recommend we gauge performance?

If this app does what it claims, how can we verify the results?
