Great value
Color: 14Pcs Eufy E25/E28/C28 Bags
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.
