    "Michael has done an amazing job with all the themes. I'm a happy customer and Lexington Themes is my go-to whenever I want to build web pages. Even if you don't (want to) use Astro, you can just drop the components in your favorite framework and it'll just work. I mostly use Remix and these themes have been so helpful and saved me a ton of time. And there's no subscription! It's refreshing to pay for something and own it and also get lifetime updates. Lexington themes are worth every penny."
