User Replaceable Sensor Cartridge for KETOSCAN Smart Breath Ketone Meter

Superó mis expectativas igual de preciso que examen en sangre!

The breathalyzer does give some data , but it’s not as accurate as a blood keto monitor .

I have been using this product for a long time but am extremely dissatisfied with it because it is supposed to be good for 300 uses. However, more than half the time, it is only good for 100 uses if I am lucky, and sometimes even as few as 40 uses before it starts giving bogus results, such as “0.0” again and again, to the point that I have to throw it out and use a new one. The producer of the product doesn’t seem to care about either customer satisfaction nor the integrity of their own product.
