neffy® trainers contain no medication and are used for practise/training.
They can be reused (unlike the actual neffy® used in an emergency which contains only one dose of adrenaline and cannot be reused).
Trainers are dark grey compared to neffy® adrenaline devices which are white.
It is very easy to press the plunger on the neffy® trainer. This is different to the real neffy® where the plunger must be pressed HARD.
