These worked flawlessly with my eufy vacuum, no suction issues or anything. They seem to be just as durable, plus the same size as the name brand ones but at a fraction of the prize. It was very easy to use them. Just pop the old one out and pop this one in. Over all I’d say these are a great value for the money. Same size, same quality, much better value.
