The brushes are very light weight, which was disconcerting when we first picked them up. How could something this lightweight be quality? After using each (the paddle for apres shower and detangling and the round for blow drying), we can assure you that they are. The round brush works especially well because the boar bristles help grab your hair and smooth it out. The lightweight brushes also kept the weight of our carry on down on our trip to San Francisco. The only problem we've had is keeping track of them in the house, everyone wants a brush for themselves.
