I think that simplicity and price
are pretty compelling reasons. For around $40 I can get a combined anode-line cutter that is trivial to install, even underwater. The anode alone would typically be around $10-15. I've been looking at line cutters lately, and they are very pricey, even the simpler ones are around $400-500. Another reason is that some boats don't have enough space between the shaft tube and the prop to install a more traditional line cutter and an anode - by combining them that becomes a manageable problem.
Also, if you need a quick, temporary solution, this is can't be beat - I was going to use the term "no-brainer", but I've seen how sensitive some people on this forum are ;-). I like it and am going to give it a try. If it sucks, then it's a cheap experiment
