Re: "WOW! But what if you live in an area that has poor signal reception?"
The scale connects to your account through WiFi -wirelessly- [that is using your modem] and not through 3G [that is through wireless telephone networks] so it works perfectly regardless of 3G carrier's signal strength.
If you want my opinion I highly recommend you go and buy it. It's use is seamless, flawless and gives you a feeling of joy and control.
