Delivery took longer than expected considering it is shipped from the Nederlands. The app is not very user friendly and does not offer options to analyse the readings more detailed. If you are not willing to allow Keto-Mojo access to your data by uploading to their cloud, it looks like your data will be deleted from the app after one year. Also, German custumers seem to be considered second class. Keto-Mojo demands a surcharge for Germans on its price offers, sent by e-mail, of almost 20% (today's original offer 55,00 €, actual price 65,45 €) plus shipping, which seems highly missleading and unfair, in my opinion. Unfortunately I was not aware of this, before I bought this expensive analysing kit. So, switching to a different provider will be an additional investment.
