This is a game changer for many situations. It is optimal for situations where the user is far from medical care, or where taking the time to access medical care would be a problem.
Pros:
-Any person can use this device, no medical training or experience needed.

• Can be used when access to emergency care is not available.
  Cons:
• Cost of about $30 USD for a small wound kit is steep.
• Otherwise very little downside.
  As a family physician I think this looks like a really good option for select circumstances.
