The bags are indeed not the original goods, but function properly. The same applies to the motor protection filter and the microfilter. I have ordered for the second time and will do it again.
The pity is that, although cost of the same company, an additional order (eg the smell sticks) in addition Porto, although the bags are free shipping. If you order the sticks to this extra shipping costs, although they are still sent in a package (can). Here improvement would be necessary. I would certainly be ordered additional hardware, the delivery would be free.
Still, I highly recommend this bag very much!
