| Re: Need your feed back Hi Stephen, Welcome to Rebreather World can you tell me the difference between medical grade sofnolime and rebreather grade? Is there more stringent testing done on the Rebreather grade or Medical grade? I know some people use the medical grade that changes colour in there Rebreather. I am just curious as to what the difference is between the two products and also how accurate is the colour change indication? I look forward to your answer. Louis |
