heres the problem.
The supplier is swearing up and down that they 'make' these. I'm inclined to believe them after looking at some of their pictures. They are telling me the flat top ones are the 'old' version and the cone topped ones are the revision. They supposedly sent me some of the old version on 'accident'. I've confirmed with a couple other users now that they all have the cone topped. ALl my replacement heads appear to be cone topped, my minis all seem to be cone topped (all the minis I have left anyway) and it appears that many of the regular novas I've sold have the cone top.
They are telling me that future orders will all be the 'new' version. So no worries there, but they deffinitely aren't going to be compatible with the proper Vision vivi nova. Mine is fully functional, I'm a little annoyed at the fogging tank on some users and not on others, but I can't seem to get a real answer. ALl she can understand is that it is polycarbonate, she doesn't recognize that there are different grades of PC. I'll keep digging.
I've removed mention of vision and 'original' from my product listing. I'm going to take some fresh pictures when the next batch shows up of the actual product out of the box instead of just trusting the freakin supplier to give me accurate pictures. I think she just googled it and sent me the first thing that popped up. If I don't get a good set of answers tonight, I might be out of stock on vivis for a little bit as I hunt down a different supplier. If she can give me some semblance of a good answer to my questions I will most likely continue to stock this version though. It 'is' performing well, I like that the isolator (the little piece of mesh inside the cup) isn't in there, and the airflow is nice.
The device IS performing well, the primary concern here is consistancy in my batches so I don't end up with diferent revisions and people are questioning it's "lineage" so to speak. That I can clear up, it doesn't make it a bad product though.
