When my original brush wore out, I ordered this because Electrolux needs to be made out of gold or some other valuable material. This replacement works fine. I haven't had the problem that others have written about where the bristles come out of the plastic holder. Appears to be glued well. But the bristles themselves are of lower quality and stronger than the originals. They're a bit softer and look like they could end up either tangling a bit or wearing out faster. But that's just the impression of using it once or twice. It doesn't have much friction when you mount it on a stick, and it tends to twist a little at the end of the stick. But not enough to render it unusable. Overall I think this is a good replacement for the Electrolux toothbrush.
