I really like it, but it does need pretty intense lighting. If you aren't at a minimum of 5 wpg it will bleach out. Mine still looks really good, but it isn't as bright in color.
In front of the Proserpinaca palustrus here you can see egeria najas which is a finer leaf version of elodea. The amount I got of this was one head that was 1" tall and had no roots. It was origanally ordered, and all but one tiny head died. Amazing stuff.
