Garmin Index S2, Smart Scale with Wireless Connectivity, Measure Body Fat, Muscle, Bone Mass, Body Water% and More, Black

After purchasing these from Amazon UK, I received an invoice from FedEx for £39.07 for import duty, argued that Amazon were the importer but they wouldn't budge and I've had to pay this. The scales look good, weigh accurately but as for some of the other features I'm very dubious of their accuracy. For instance if my weight goes up by 1Kg after the weekend it shows my muscle weight being higher by a corresponding percentage which of course is nonsense, similarly if my weight goes down. The initial body fat percentages were far higher than the professional machine I'd been using but Garmin say in their literature if you have your own figures from a Dexa machine or similar to manually enter these body percentages and then miraculously it simply mirrors them going forwards, altering the muscle mass as your weight varies week to week. It seems that they know their own machine isn't accurate - A waste of money if you want to measure performance /gains over a period - according to these scales and the way they work, all I need to do is stuff my face to put on 5Kg and it will say I've put on 1-2Kg of muscle, regardless of the body composition.
