Gadget seller Firbox is promoting internet connected bathroom scales this year, which we reckon you should avoid. The device automatically beams your weight, fat mass and body mass index to your PC or iPhone each time you step on it.

It does this via WiFi and worst of all it can share your intimate details on social networks like Facebook and Twitter. What a lovely idea for someone you know to be able to do this Christmas as they gorge on festive treats.

It’s a great present if you want to offend someone on several levels, suggesting they need to lose weight and then publicising this to hundreds or possibly thousands of people. The scale does have a pretty good design but the price of this high tech bathroom accessory is a whopping £119, another reason to steer well clear.
