This set I bought mainly because of the extra-soft brush for surfaces and am thrilled. Since I have this brush I really dove so from almost everything. The other brushes in this set are super, the Flexi Crevice tool I use very much, only the mattress brush I use rarely, because as an accessory was with my vacuum cleaner has a mattress brush case, the one piece is indeed small, but the device is mounted. But it's just a set and that includes this brush. The price I find fine. Accessories from Vorwerk or the like is far more expensive and thus offers Dyson in this set of quality and price!
