WARNING! It came to our attention that there are or were several Chinese websites selling the Scalewatcher Nano for an impossibly low price.
When one is tempted to buy and happen to look in the list of countries where they ship too, one finds that shipment is throughout the world, except China. This alone indicates bad intention.
So far we were notified of the following websites:
“ “ and “” of which the owners are located in China. Both are not on line anymore.

If you come across websites selling Scalewatcher units against discounted prices please inform us and we will investigate wether the website is from an authorized dealer.
