I’ve been using CrazyLoad for months now, and the difference it makes is so noticeable that I forget what my store used to feel like before. I only really remembered when I temporarily disabled it during a theme update and everything suddenly felt… slower, heavier, almost sticky. That’s when it hit me just how much this app had been doing in the background.

What really surprised me was how much it changed customer behavior. People are staying on pages longer, browsing more products, and my bounce rate dropped almost immediately. You can tell customers feel the difference even if they don’t know why.

Instalei o aplicativo mas ele além de deixar meu site ainda mais lento, tirou a minha página de Checkout, perdi várias vendas em menos de 24 horas, uma lástima. A sorte é que eu fiz um backup do meu tema e apenas troquei, porque o app estragou bastante o tema em que foi instalado. Pessoal da Crazy, vocês são Crazy mesmo, pois assim acabam com a vida dos lojistas, esse aplicativo deve passar por revisão urgente. Não recomendo!

Terrível, não melhorou desempenho e quando desinstalei, o app não removeu todos os códigos após desinstalação. Ele ataca o head do theme.liquid e altera sua estrutura de menus e outros... Me gerou uma grande perda de tempo tendo que restaurar versões para corrigir.

Don't download this app without a backup for your current theme. This app crashed my site completely. Very devastating experience, especially after hitting #1 on search results on Google.
