If your life or someone else's life is in the equation then don't back out of buying quality gear. And that doesn't mean the most expensive, that means the best quality that holds up. Name brands are a good start, if you consider a new brand make sure they are transparent and actively sharing their products benefits, uses, instructional videos and purpose so you can see it before you are relying on it.
We are not a name brand, but we share everything, and show everything to give complete transparency.
