The quality of the brush exceeded my expectations. I have the four pods, but havent mounted them yet. My only reason for giving 4 stars is that the back strap doesnt adjust and I think I have really skinny ankles because the strap wants to fall down when I tried them on. For the price these shoes are 10/10 especially! I was sad to receive a pair with one shoe that looked very used and the other shoe mildly used. These worked perfectly for holding my Airpods Pro in my ears. It is useless to pay a premium for Keens if the quality is not there. You have the same reception with or without this antenna. But for now, it?s fine. WOULD LIKE TO BUY THE BEIGE COLOUR IN MEN 12 X-WIDE.
