Thank you for your feedback! We appreciate your kind words about our Wilbarger Therapressure Brush and are glad to hear that you find it helpful. We apologise that you feel our product is expensive and doesn't last long. We do try to keep our prices reasonable. There are also options to choose larger packs of brushes which reduces the cost per brush slightly. Regarding durability, the Wilbrager Brush is designed to be soft, but to give firm pressure input at the same time. That combination of sensory stimulation can be tricky to balance regarding durability. Thank you for choosing our brand!
