My cardiologist recommended this product. I read the reviews in the APP store and was concerned regarding tech support. The medical reviews of the technology was sound and had a stamp of approval from the FDA.
Though I have only used the device for 2 days; I can report that I contacted tech support pre-purchase and found them to be responsive. Not immediate but next day. After purchase, I had what seemed to be interference with my bluetooth vehicle system. I contacted tech support and they responded within 12 hrs or so, I had a follow-up question which received a timely response.
The bluetooth issue has not persisted, though I have seen a complaint in the APP, so I am not sure if it was a coincidence or not.
All in all, customer support has been good.
