I thought between Khubelino and Chinese fakes. I'm glad I chose Hubelino because it's very compatible with Lego Duplo. There were no step-by-step instructions in the box. You need to download the PDFs from their website. For some reason I couldn't get the Hubelino Android app, but I don't mind. It's a bit pricey, but I'll definitely be buying more expansion kits.
