Bests & Worsts Reviews from Amazon

I should have listened to the previous reviewers, particularly the one where the person said their doctor said this was garbage or something like that. It's wildly inaccurate. I compared it to my standard one, which isn't that old. I thought this small one would be easier to use. But it was so far off the mark that I don't even trust it. Please don't waste your money on this product. It's not good for your health.
