From Todd's post here.
I'd personally like to see some testing/occlusion rates on that tourniquet before trusting it. It doesn't appear very effective. The evidence based trend is to use a wider compression surface (see the SOFT Wide vs regular SOFT, as one example), whereas this is very narrow and even in a video the inventor admits it must be wrapped properly to form an overlapping, wider band to achieve adequate occlusion.....the whole idea kinda going against his misuse of the terms fine motor skills, to begin with. Even if you're with it and calm, I can't imagine this being a very easy thing to accomplish in a quick amount of time. I imagine with movement and what not, there is great potential to displace the wrapped band as well, causing it to lose compression area.
I'm not impressed, and I'd much rather opt for the rubber therapy band-like SWAT-T for a pocket kit. Do any of the SMEs or medical guys on this forum have experience with this RATS tourniquet?
