They have a syringe grip. Call Shared Solutions and ask for yours. it slips over the needle/syringe body and provide nice wider wings at the top end to grab onto. It has saved me from having to use the auto inflictor several times. I have also found that once buried in my bum I can let go of the needle and it doesnt fall out. that gives me a chance to re grip.

There is plenty of time to learn both ways.
