Product review (5 stars): Glass half-full?
Do you like to play the lottery? It looks like the reviews are fairly bimodal, with a split between "blew immediately" and "works great," so I put my $3 on the line and let the chips fall where they may. I cannot speak to longevity, but I can now see clearly that the glass is filling with water, and it has brightened my day to have a working dispenser light *and* to have won the lottery.
