SP,
I have some.
I have not needed to actually use them yet, but I have opened one up for use as a "training aid". In that respect, they work as advertised. You can use them one-handed (best to practice this before you need it, it is a little tricky until you get used to it). I'm no expert, but they appear to me (no stranger to field dressings) to be a very good product. I was VERY impressed. A one-handed trauma dressing is a Godsend to our troops, and damned handy for everyone else.
BTW, the company that makes them---H+H Associates and Inc.--has the BEST customer service of any company I have ever done business with. BAR NONE.
Take care,
Andy
