I have never heard of these tests but plan to do some research on my own.

I have the AA and I question how someone could wear them to 2 months. I have stretched mine to 1 month of use as opposed to two weeks only because I don't wear mine everyday or all day?

My biggest concern with them since they are so porous and water soluble I would have concerns on them being "bacteria" free for that length of time. And not prone to causing eye irritation since they aren't designed for that length of wear? But, guess alot might depend on how they "feel". I can tell with mine when I can't get them clean anymore or they just aren't comfortable anymore that it is time to break out a new lens.

At the minute cost of them for the convenience I can't see risking the health of my eye just to spare a couple bucks. I can always buy more lenses but I can't buy a new eye.
But, everyone has their own opinion.

Hope this helps in your research
