Query: BP Toy

I bought this thinking it would be a good tool to take quick measurements. This device is completely inaccurate. It is not worth the free shipping let alone the purchase price. If you are really hypertensive or suffer from some sort of cardiac myopathy, I would suggest steering clear of this. I didn't realize this was an "as seen on TV" product. Epic Fail!Update: I have found wristcuffs useful in my line of work as a screening tool. This particular one is trash. I would advise sticking to name brands. Any positive reviews on this product are fake.
