First of all.. I'm not an expert. 2-3 years ago I had a play with prusa i3 copy. I spent over half a day assembling it. Then a lot of time on corrections over few next days. I decide to try with that model due to high selling, good opinions, and after reading some reviews. Basically i was expecting the same issues here, with a slightly better printing quality, because it was hard to believe it is as good as I saw on youtube. I am extremely surprised! It takes me 2 hours on assembling. I did the test print of included `dog 2.5 model`. I was waiting to see how many corrections i have to do. When i saw the results after 20 minutes, it was like `oh my god it's perfect`. I had to stop at 98% as you dont provide enougth PLA, but nevermind, the quality gave me so much satisfaction that I will walk happy the whole week! I am also happy with the parts quality, with the ease of assembly, each parts was well indicated and named, theres no way to pick a wrong screw , that's fantastic. I am very happy that the product was packed professionally and securely. You got me, don't know at the moment if I will need something bigger, but definetely in case I'll need another 3d printer I'll rely on you. And I'll recommend your product everywhere and for everybody. I felt I owed you this review. Thanks from a ultra-satisfied client!
