Hello -
It does not seem to be possible to purchase your magnetometer current sensor (https://shop.moderndevice.com/product/current-sensor/). The "Add to cart" button causes "Current sensor has been added to your cart" to appear, but when one goes to the cart, it is empty. This occurs on every browser I've tried, on multiple computers running different operating systems and belonging to different people. Moreover, I can add every other item I've tried without trouble. Unfortunately, the item I actually want to buy is this amazing looking current sensor. Please help!
