I am going to get some syringes for fear of breaking my pen, I've used hard twist twice successfully but always worry I may break it and I don't want to waste any liquid.
So my question is do you put the needle all the way in your skin, some people say go at an angle some don't.
I've watched a few videos and they just Jam it in..
If I get 6mm needles that's bigger than the pen needle, does it matter?
