Hi I’ve had the same problems with the cannulas with the insight, last week I checked BG at around 7.30am BG was 6.5, I input my carbs into the insight meter my insulin then went in, ate my carbs. At around 12.30 I checked my BG and it read 15.1 & this isn’t the first time this has done this to me. I’ve also checked my BG on the insight 3 times with 3 minute intervals and it read 3.4, 5.2, 6.9 I have lost faith in the insight & often think about switching back to my old Accu-Chek Combo pump. I’m hoping that in a years time when I change my pump, I’ll go for a Medtronic. I must also mention that I’m in my 57th year of T1 diabetes.
