I have been using this tool for about a month now and I must say it's a great tool. It's really cool if you want to have a dark website instantly.

However, I have picked up a really big issue with this tool and that comes down to the page speed. If I deactivate this plug-in and test my page speed, especially on mobile, my speed is literally a hundred times faster. However, when this plug-in is activated, my page speed drops by a lot.

So, this plug-in, although it's great and useful, has a big downside: it really affects your page speed. Unfortunately, it's unusable for me because, as you know, load speed is one of the most important factors for a website. If you have a really slow loading speed on your website, most customers leave or bounce, and it affects your SEO ranking as well.

So, although it's a great tool, unfortunately, it's not so great when it comes to page speed, as it affects your page speed.
