Avoid slow and fast mistakes

For people with children it is an invention

I am not mistaken with the feathers (for the moment) but with the quantity, it is all so mechanical that sometimes I do not know if I have punctured the dose that touches me ... I have ever had to get faster for injected I missKnowing that I was going to need more with that meal.
The feathers are comfortable to me and I speak to you that the first ones put them 10 years ago for fertility treatments.
When I debuted there were no needles in the emergency room and I spent 3 days extracting the insulins from the feathers.A roll.
What I use in syringe is heparin and is horrible.The needle is chubby and long, let's prefer the pen.
