Well, my two M-20's put out a lot more than any other medical concentrators could. They are still humming away! This is an update after months and months of regular use. If I could go back in time, I'd have bought them SOONER!
I am so glad I took the leap of faith and got these units. Like every piece of equipment in our industry, it will fit some better than others. If this is the worst bit of negative propoganda Larry can find to post about his competition... the new M-10'2 and M-20's must be relatively problem free now.
I'm happy happy happy with my investment.
