Looks like a scam!!
I received the wrong product. Wish I had read the reviews before I bought the NonInvasive Metabolic Device, I got a finger pulse oximeter in the mail. It was send from linda-lax in Gardenia, CA, I tried to go thru SpeedX to get to the company. They wanted my credit card number and were charging me $2.00. I already lost $50.00, so I didn't finish with them. This is a SCAM. They spend a lot of money on advertising and nothing on customer service.
