    i’m with you, I like the pump but filling the cartridge and getting all the air out is a constant piss off.

    I like the look of the T-slim but this reservoir looks overcomplicated to me, compared the simple clear tube used for the medtronic 640G. This makes me tentative about getting a t-slim.

    I have a Tandem t:slim x2 and have come upon this problem. In past supplies I have always received a 26 gauge 1/2 inch needle which works very well in filling the cartridge. The past order of supplies has a different needle, a 26 gauge 3/8 needle. I have found that this new needle isn’t long enough to reach the fill bag inside the cartridge. Has anyone else found this to be true? I don’t know why they take a working product and replace it with one that does not work.
