One star for the company
One star for the company, five stars for the bogist C1 pro product. The product is excellent but asking the company some questions (by email) they gave me answers that showed me that I have nothing to expect from them. They won't solve your problems, they just sell products nothing else. They seemed so incompetent even with simple questions that it really makes me wonder, if (at least) this product is theirs. So get a product (they look and probably are, very good and at a good price) but whatever happens, look elsewhere. Strangers on youtube can give you a solution, videos on youtube can give you a solution, everywhere / anywhere you can find a solution except the company. They will tell you regardless. I know, it's frustrating, but I lived it. I'm not telling lies. For anyone who wants, I can send him the correspondence I had with them so you can see for yourself what answers I got to questions related to their (for heaven shake) product.
