Actually, I had ordered my set to tell the mites to fight. Our Mopsdame other hand, is allergic, but does not hesitate to (illegally) on the sofa. Your symptoms are not improved. Today, the parcel arrived and the mattress top to the mites was equal tried. Whether it helps against allergies, will only become clear after a few weeks, but a great side-effect: the annoying Mopshaare can be easily removed from the sofa. Even from the pillows and the dog blanket. The other essays: with the Flexi-joint brush I come at corners in our narrow bathroom that I had given up. The accompanying and included in the set brush attachment is very strong, so I could easily remove stubborn dust. The soft brush saves on many surfaces dusting. All in all a super product.
