ANOTHER REASON NOT TO TRUST THE INTERNET OF THINGS: Nokia will disable the key feature of its priciest scale.

Nokia has announced that it will be disabling the headline of feature of its Body Cardio scale in a software update. The scale was sold with the ability to track Pulse Wave Velocity (PWV), essentially measuring the speed at which your blood flows through your veins. The slower and more constant the speed, the healthier you are, and vice versa. In a statement, the company said that the feature “may require a different level of regulatory approval,” possibly risking the wrath of regulators.

Like most smart scales, the FDA initially considered the scale as a “wellness device,” requiring little in the way of scrutiny. In the last two years, however, something must have changed for the company to suddenly row back on both selling the device, and deactivating existing units. Users are told that they are unable to opt out of the software update, which is coming on January 24th. In addition, the device itself has been withdrawn from sale until such time as the hardware can be altered.

Owners paid an $80 premium for the scales, and will reportedly receive a full refund if they return them, or a $30 refund if they chose to keep them after they’ve been gelded.
