This thing is a toy and so much more. It may look like a toy on the outside and when you first start the software. But the more you get into it the more powerful you see it is. Its great for some one to get started into controllers with no experience in coding but very powerful for the more advance user. Also the support in the forum from the users and the company (even the inventor) is awesome.
Cette chose est un jouet et bien plus encore. Cela peut ressembler à un jouet à l'extérieur et au premier lancement du logiciel. Mais plus vous y entrez, plus vous le voyez puissant. C’est génial pour certains de se lancer dans des contrôleurs sans expérience en codage mais très puissants pour les utilisateurs les plus avancés. De plus, le support des utilisateurs et de la société (même l'inventeur) sur le forum est impressionnant.
