Their ifak refill kit is 100% worth it they have the best deals on tourniquets that actually work don't buy the cheap **** from Amazon cuz they don't work and the next best course is spending 40 on one when u can get 2 for 25 at rhino rescue!!! And the ifak refill kit comes with everything u need I bought everything for my first kit individually and thot I saved money then came across these kits and it's a lot easier and cheaper!!!!
