Great find & a great price !
I am ordering one --how about you ?
I now question why wasn't something like this on the market years ago?
Simple but so effective

I already have one.
The question I have is, if you don't use something like this, do the other methods of rising adequately rinse that area between the LPI connector and the internal valve? Obviously, that area SHOULDN'T be exposed to anything but nice clean air from your tank. But, well, shtuff happens.
The garden hose attachment for flushing may be unnecessary, but it seems like can't really be a BAD idea. Unless, of course, your garden hose turns out to have stuff in it that you don't want in your BCD...
