We've been using this replacement vacuum accessory for a few weeks now and we are very impressed! Based on our own experience it fits perfectly into our Electrolux Discovery Upright and works as good as the original part .The suction power is excellent, it picks up dust and dirt with ease. The only con is that it's a bit pricey for a replacement accessory, but we think it's worth it for the quality and effectiveness. Overall, we highly recommend this product to anyone in need of a replacement vacuum accessory..
