I took it with good discounts for 8 somewhere. In general, the thing is worthwhile if the price is less than 12tr. Pros: Everything is fine, the traction is perfect, it sticks tightly to the floor. Very convenient all made to clean the bag. Can be washed even in water. Soundly assembled, nothing backlash and does not creak. Small in size, great design. It doesn't make much noise, you can't really complain about the noise. As for the HEPA filter, I didn’t specifically test it, but it seems that it definitely doesn’t let dust through in the blowout, that is, everything remains inside the vacuum cleaner, blowing clean. I'm not talking about allergens here. With its cons: Of course, the volume of the container is quickly clogged. It is fully enough to vacuum a kopeck piece 40 meters once and it is already worth shaking out the bag. But this is not a problem, since everything is very simple to do. The wire is short, this is perhaps the most unpleasant thing in the whole experience, but again, tolerable in the light of other advantages.
