Better ship it as a ~20 euro item. Now I had to pay customs tax, increasing the end price by 50%.
Works and feel ketones for sure, but measurements depends on how you flow so better to measure all time same style. Later will try to compare with blood and add comment.. Seller best in any case.
Works as described, but I'm not sure it's calibrated properly ... showing too high values (4.10, like I'm in a starving ketosis). Will test it thoroughly.
