Hi there, We have just received our upgraded Animas IR2020 after having two IR1200's develop cracks in the battery housing area. My son has been wearing the new pump for about three hours and it has developed what looks like white scuff marks on the screen. In the Upgrade information booklet it mentions the new factory installed plastic display lens protection film that is not to be removed. I have tried gently rubbing the marks to see if I can remove them but have had no joy. Has anyone else experienced this? Is it normal and just to be put up with? I would appreciate any input regarding this. Suzanne, New Zealand. Mum to Michael age 14, dxd type 1 age 4, coeliacs age 5. Pumping nearly 8 years. Mum also to Daniel 16 and wife of Paul.
