I have used Jc exclusively for about 6 weeks now. I have had no issues about color, off taste, etc. I also must be in the minority. I have heard that more people do not like it than do. I use artic mint, black cherry and original. I have not killed my atomizer, (knock on wood) using it exclusively for 6 weeks. Same atty. i heard attys normally do not last this long, must be a fluke, but i do not dip or drip either. Just constantly top off on my 510. The only complaint I have is that the flavors are weak. I can detect them, but ever so slightly. I have heard that my 510 might be doing that also. Mabye more flavor out of another model? I like the fact that the juice is made about 30 miles away from me. I just wish the flavor was more pronounced.
