The pull stop connected to the main tube doesn’t create suction - WTF
The pull stop / tube doesn’t create suction when engaged. This product is marketed as a first aid device to draw fluid from a small opening in your skin, you can’t even pull skin up into the tube.  I bought 2 for my med kits and neither of them work so it isn’t a fluke. I would not recommend buying. there is only a 30 day return window and of course I only just found this out when testing the item. Thank goodness I didn’t rely on this product working in an emergency
