Fitbit Flex 2 Swim Proof Activity Tracker

This product produces magnetic fields and Radio Frequency waves, which are not described in their advertising, instructions, product descriptions,specifications, nor on their website. I had foolishly assumed that it was PC/Windows compatible and came with a USB cord, that it communicated to my PC through the USB cord. After an hour of trying to sync, I discovered on-line, that I needed a special USB device, sold only on their website refurbished. The shipping cost was almost as much as the cost of the product. I had continuous 5 day email communications with Fitbit's Customer Services. After several messages and searches on-line, I found that the device, which must be worn 24 hours a day seven days a week,operates and communicates with a PC via Magnetic fields and Radio Frequency waves. This concerned me because I have a Pacemaker/Defib implanted in my chest and this device comes with warnings about exposure to magnetic fields and RF signals. So I asked Customer Service for help. I asked them to please call the Implant manufacturer and they will determine if it is safe for me to use. They told me I should do that. I told them great answer, except nowhere in anything you publish on paper or on-line, do you provide the product Specifications. They still refused and said the FCC said they didn't have to and that it was negligible like cell phones. I told him that you don't wear a turned on cell phone 24x7 and I have warnings about keeping cell phones as far as possible from the implant. They still refused. So I asked for a product return and refund. After another two days of messages, I was told that Fitbit does not accept returns unless I bought the product directly from them or from an authorized dealer and that my seller was "unauthorized" I argued that it was not the seller's fault it was the omission of important safety information by Fibit. They still refused. They did however agree to the return of the special usb device (less the shipping costs) It is very disappointing because the Fitbit device appears to be everything you would want or need. Therefore, I would not recommend Fitbit to anyone who has an implanted device and anyone concerned with long term constant exposure at skin contact to magnetic fields and Radio waves. Also take into consideration, Fitbit, unlike most reputable companies, does not stand behind their product enough to accept returns no matter where you purchased it, and their Customer Services are less then helpful. You can perform an on-line search and find the product complaints yourself.
