I'd say it's kind of positive/negative review. The front part of the head doesn't fit well, not like the pictures no matter how you print it, it is bigger than the rest of the head. Most of the parts, you gotta lay down before printing, otherwise they'll easily break due to orientation. Hm let's say it like this: if you print them the way they come, they gonna break. This model is excelent but still need refinement.
