I ordered a blood pressure monitor from HRM USA. It read several points below my old monitor, another new monitor, and my doctors office. I returned it for a refund. After deducting their shipping cost to me (originally free), a 15 % restocking fee (the product was returned in perfect condition), and my shipping costs back to them, I actually received a refund less than 50% of what the item originally cost. I will NEVER do business with them again. And, I had ordered from them in the past. VERY poor business, in my opinion.
