Familiarise with how to use Jext® by practising with the Jext® trainer.
The Jext® trainer is exactly the same as the ‘real’ Jext® except for 2 things – it doesn’t contain any adrenaline and it can be used repeatedly. It works in exactly the same way as a ‘real’ Jext®, so it is an excellent way of teaching yourself and others how to use Jext®.
Use the ‘How to Use’ steps, and/or the demonstration video on how to use Jext®.
