Do you mean the new experimental insulin delivery with GRVs. ?
or the blood glucose measuring patches also experimental ?
or the herbal remedy that some claim to be a cure for diabetes ?
The first two I believe are not generally available yet the third as far as I can see is just another herbal remedy most don't work as well as claimed in my experience.
Good diet and exercise would probably be as effective if not more so.
But to answer your question I have not used them successfully or at all for that matter.
