I've used these in the ER and OR. It is easy to use, good closure BUT. This is wound closure, not recommended in the field. The wound needs to be meticulously cleaned first. It would hurt like Hades to use this without local anesthetic ( lidocaine). If you believe that girls like scars, you'll love this - prominent scar guaranteed each use. I keep some around to patch up pets and livestock, I use suture on the humans, usually after taking them to the ER, so I've got the stuff to do it right the first time. This would be good if you're way off the grid. or maybe combat situations, or if you really like scars.
