Just listening to some of the threads re photos etc. People are now questioning why more questions weren't asked at the time of posting. I think it is now time to ask more obvious questions.
One such question relates to when the 20,000 batch was returned. Reading Tricops post, I read the section stating that the trial will be reduced in time and quantity [5000] to and I quote 'allow sbl to manufacture an IMPROVED VERSION of the oraline 1v product'.
Surely the question must be asked of sbl, of what improvements were supposedly made to this batch of 5000 units?
SBN have not informed us shareholders in any way, shape of form, what these improvements were to this final batch. Again treating us as mushrooms.
To me, this wording does NOT indicate a QC issue. I say this now knowing that the units were not produced by siyi but the the Chinese OEM factory we have been using for sometime. If it was a QC issue, why would they state that there was to be an 'improved VERSION' to be made? The would just remake them, ensuring that the QC was enforced.
AND I don't believe this 5000 'improved version' batch is related to the temperature issue as they plainly state that over the next few months that issue would be addressed.
PLEASE SBN, enlighten us as to what this new and improved version, comprises of. MPS had already passed the 'original' version, why would they need to improve it?
