[QUOTE="iHs, post: 174366, member: 8799"] Hi Wendy I've also had loads of problems with the E4 occlusions but have stopped using the Flexlink and Flexlink Plus for a while and am ok at the mo (touch wood) with the Tenderlink. I dont think the problem is with the cannula kinking as I've just had a go at activating the set without inserting it and the cannula remains straight when withdrawing the little white block needle flip thing. I think there is a design flaw in that the needle inside the tube clip that delivers the insulin is not quite long enough. It barely pierces the membrane and there is a significant gap between the tip of the needle and the cannula itself thus making a void. If the needle was a tiny bit longer these sets would be ok but as they are, I think lots of people will find that they have to put a new set in every 12-15hrs or face having higher bg levels and then the E4's. If you have some 8mm disposable syringes lying about try to insert the syringe needle into the membrane and then you'll see for yourself how far it is able to travel into the membrane before you hit the cannula, then look at the tube clip.
