Flash: Page Speed Optimization , 42 reviews

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 !

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

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.

Good app if you have a problem with the speed of the store

I've already uninstalled the Flash app from my Shopify store admin, but today (April 12th), $19.90 has been already paid automatically - which I can't understand. I've already sent out 2 emails to marc.mayr@flash-labs-sia.intercom-mail.com & info@flash-speed.com. I sent another email today. Please check my emails and give me back my $19.90. Thank you.

Stay clear of this app. DO NOT INSTALL.
contacted support 6 weeks ago, no response. Customer service non existent.

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.

For anyone with a 3th party checkout app ( I have a Cash on Delivery App to reveice orders) dont install this app. I had the issue that customers couldnt checkout because the checkout app was getting blocked. After a night figuring out why customers could check out. I uninstalled the app and removed the code in my theme. For the few days the app was installed ( not used ) i payed 20 dollars.

I am writing a review because it is the only methode to reach you. I cant use customersupport , i have to install the app again

WOW! I have been struggling for so long with my site speed and Flash just fixed it in a matter of minutes with almost no effort on my part. I honestly cannot believe how great this works. I was paying for another service and constantly had my speeds dropping into the 30's. Since installing Flash my site speed has been between 90-100 for both mobile and desktop. I cannot suggest this app enough.
