This is my second purchase of this scraper. The first lasted several years. We have a fairly deep acrylic tank and would have liked a few inches more length, but overall I'm very happy with this product. The tool is nicely shaped and it's easy to apply sufficient cleaning pressure to the tank walls. I use it for stubborn green algae that my otocinclus can't help with. The price of this scraper ($6.59 on Prime as of this writing) is very reasonable.
