Great graphics, but easy to get disorientated without needle being depicted.
Possible Improvements;
1) Narrative during procedure rather than "sedation music."
2) Reference to point types and body styles desired.
3) Hints such as how to avoid the swage with the hemostat to minimize needle separation.
Well worth the money, just need to put a bit more effort into it to make it a "must have" for practitioners.
As we say in Kansas "There's more chicken left on that bone."
