I have a video somewhere of me scraping a weeks worth of algae off my 300g. It is well worth it just for the time saved. The video is buried under a years worth of other videos, no promises but I'll see if I can track it down.Not heard of these, do they last longer than the steel bladed or work better?
I've had the upgraded scrapers for a little longer than a year and have replaced the blades once so far. When they start to sgow signs of streaks, I just replace the ceramic blades themselves. There's a link for those on the site too.
Do you have a link?

How long have you had them? Have you had to swap out the blades yet?I recommend this as well. It is awesome.
