That's a bummer. Mine has worked flawlessly for about 8 weeks now. Hopefully I don't have issues when I change out the fleece.This product has been one of the worst experiences I've had with equipment in this hobby. literally everything that can go wrong with this thing has. even think they gave me one of those fleece rolls from that bad batch because every single time it rolls new Fleece it causes my skimmer to explosively overflow with bubbles to the point it almost filled my whole cabinet with bubbles once, and it takes 2 days for the skimmer to work properly again. its getting progressively worse as well with the "bubble episodes" having a more explosive reaction each time. I didn't have any of these issues before I put it in, and I have to say this whole experience has made me pretty bitter with fleece rollers in general. what's even more concerning is this is the gen 2 model. sad to say but this product did more harm than good in my system. last a week in my system before I had to remove it.
