“Very pleased so far! I thought long and hard about which device to buy and in the end, although some may think its a waste, I felt the longevity of the individual sealed strips would maintain their quality as ive heard some can expire which is a waste. Also someone had reviewed it as being difficult to use but I synced it up to my phone and the app so I can keep any results to hand and it was straight forward and I'm clueless at technology!!I've had some great results from testing. Hit my fasting into 4.9 ketones which is great! Its fascinating to have a more in depth idea of what your body is doing. Would recommend if you're looking for a 2 in 1 tester for ketones and glucose!”
