Very good, but...

For the Parkside PWD30A1 vacuum cleaner, it is small. It attaches normally, but it does not touch the ground, resulting in it falling after a while due to its weight. One of them even detached the front cardboard.

For their price, around 10 euros, they are fine.

As another user said, I put a few pieces of cork inside to lift the bottom of the vacuum cleaner.

I ordered them wrong.. They look good but they are too short for the parkside pwd25 a (1400 watt).. but they fit perfectly in the hole.. and as for the height, I placed them on the bottom of the barrel with foam (about 8cm) so that it doesn't hang and come out.. the vacuum cleaner sucks like crazy.. my job is done! I just lost a little capacity.

Update: eventually, the bag hung and tore. It needed more lifting. Now I put the foam to cover 1/3 of the barrel and everything is fine.

Smaller than the originals. I was not satisfied!
Also, it did not have inside, like the originals, a bag that goes into the middle vacuum cleaner located inside the bin, resulting in causing me a problem and the vacuum not working properly.
