Hi all well In January i bought an ACU safe minitor and strips and now feel I cant rely on any past or current readings as I did a bit of experiment over a week and was alarmed to see readings on different fingers at same time 2 hrs after main meal were up to .10 difference!? E.g if was 7.5 one finger 8.5 next finger sane hand etc Anybody else use this machine? Any similar probs? Should I bin it? Did buy in a rush on Amazon
