Excellent smooth experience (as always). The meter itself is reliable and based on the NHS approved glucometer, so gives rather very acurate readings as well. Ketone measurements I cannot compare to another meter however the consistency is definitely there and by now (year of use) I can actually preditc the levels based on my diet and activity, so clearly works. I'm also hearing similar things from other users, in fact I've bought Keto_Mojo based on endless reccomendations. The customer service is also excellent, any issues, just drop them a line, they are there! Only suggestion would be to elliminate the single wrappers of each strip, or even better to make the disposable parts easily reciclable. Hurts me to be adding to the global waste and microplastic issue. Hope that the product is PFAS free, although aware of many medical stuff relying on these, so would be good to have some info on this too.
