Bests & Worsts Reviews from Amazon

I should have taken it as a warning when I found a card in the packaging offering a gift card with evidence of a 5* review on Amazon; and just sent this back right away. But I had good luck with an Omron wrist monitor for years, and Amazon was OOS with no dates on restock, so took a chance. Although this is supposed to fit large wrists, it was snug on mine. Which led to higher readings. Ok, you can adjust for that. After a couple of months my readings were getting dangerously high (like 200/120 or higher). I made an appointment with the cardiologist and took this in with me. This monitor on the left wrist gave a reading with both numbers more than 50 points higher than what the nurse got using her cuff on the right arm (which gives a higher reading than the left as it’s further from the heart). The cardiologist declared this monitor garbage and said it should be thrown out, as anything that inaccurate can’t even be compensated for.
