Have seen random reservoirs balky. Have not had any not cured by lubricating with insulin - fill with 200 units and push in and out from reservoir to bottle and back 3-4 times. Keep on Animas. Also, do an FDA MedWatch - PRODUCT if you are stateside.
I will start paying attention. I haven't had any problems but not sure I have had that batch number.
I opened a reservoir on Tuesday that had a piston that was very hard to move, I cycled it back and forth a few times and it didn't get any easier, so I discarded it. But mine was a different lot from yours. Mine was lot #B201762 (exp. 2013-10).
I've had that happen once. I have also had the whole inserter fall apart when I had pulled it out. That was also annoying and has happened more than once.
