I add to the growing number of people who are very unhappy about the level of customer support for this product. The product is good when it’s working but when anything goes wrong there is literally zero support. I reported an issue in June and still haven’t received support. I am also finding that over time this product can become quite erratic and you need to reinitialise several times to make sure it’s consistent with a standard device (e.g Omron). I hadn’t used for awhile and when first used again the readings were way off what I normally am and not consistent with the standard Omron readings. It took several reinitializations and knowing what was reasonable for my blood pressure range for the product to start giving sensible readings. As a consequence I have lost any trust in this product and particularly with the poor level of customer support. In parallel with this the two-year warranty means nothing as they don’t reply to you! It’s such a pity as the concept of the product is great.
