Sure if you got try em, It wouldnt hurt anything. If you dont like it then you can always get something else. The thing is you will never really know what you like till you try em. You may think they are awsome, others may think they are ok. Its just worth the effort. I hope they do work for you, It will save some dough in the long run.
I have a couple of the Hurricane overflows as well and ReefDaddy is right. For the money, I couldn't be happier.
Besides, they are the only overflow I've ever seen with a cover on the back siphon box. I think that it's really neat and quite useful at keeping salt creep in check.
