I have been having all kinds of issues with my infusion sets from Unomedical Animas - 26 in 9 mm infusion sets that go with my TSlim pump. I have tried the Cleo infusion sets and they never would stay on for the 3 days. I have been having issues with these Unomedical infusion sets - they start to infuse then stop and you dont know it and end up with high blood sugars which makes you constantly change them out and use up your supplies. I have contacted my supply distributor and Animas and Animas says they are aware that some have intermittent packaging problems. Does anyone have a TSlim and a infusion set that works well?
