Title: Great item!
Review: I am so happy I decided to get this tool! The 34" length is wonderful! The "rake" is sturdy enough to do a good job even with a 3-4" layer. The metal scraper is wonderful for the coralline algae and the "polisher" is on a swivel to make getting into corners a breeze. There is only one disadvantage that I can find; one of my tanks is a 42 gal bow front and the metal scraper does not swivel so it cannot maintain good contact on the bowed glass. That's not enough of a problem for me to take away a star because the product is so wonderful overall.
