What were the issues with the previous rebreathers?

I'm just a bit wary in case this version also has issues... but I feel if it works, it would be much more peaceful than violent mechanical asphyxia..

The current version is not a ReBreather, is an inert gas implementation.

The problems of previous versions were mainly seal problems. At the end of the day medical masks are not explicitly designed to protect you from the external gas, specially if you use them without a positive pressure which is something that the current version is still lacking.​

Thanks - what I don't understand is how the current one can work with such small cartridges of nitrogen etc? When the other inert gas setups have needed a big tank like the Max Dog Brewing? Wouldn't there be a risk of the nitrogen not being sufficient to ctb?

I don't know what's the total volume of the reservoir bag, doesn't look very big so it definitely plays with the known fact that cessation of breathing happens fast (2~3 minutes).​

You don't need a big tank to CTB, in fact Dr Philip Nitschke recommends in the PPeH a small 2L 200bar cylinder which is 43cm tall and weights 3,5kg. People buy bigger tanks to feel more confident in the setup, or to run tests, or to do purity checkings, etc.​
