As others have pointed out, there are other proven means of closing a cut in the field. That they are cheaper and likely easier to apply are other factors in their favor.

I see this to be much like the LMA airway that we were forced to use before switching to King airways. The LMAs worked well in a well lit, well staffed, clean surgical suite where the patient did not have to be moved but in the field where lighting is bad, patients aren't clean, and they have to be moved from often cramped positions, these devices failed miserably. This device reminds me of that.
