Kiierr stands behind its products.
i recently sent back my kiierr cap due to a malfunction, it was under warranty and Kiierr replaced it with a brand new model. i was very happy to receive a new cap because i thought they were just going to repair the one i sent back, not only that but i also received some free goodies to help with my hair program. Kiierr stands behind its products. They made feel like a valued customer.
