They dont just fall out. 1 surround on PC and was not impressed. Built my first complete wheel and trued several others. Im honestly blown away at every aspect of this fan. Were using it the carport of our mid-century home to hang raincoats and umbrellas, no complaints so far. The comfort is perfection, but the sizing is much larger than usual. no way I will own up to cheating. 4/22/20 Update: returned the 8 and kept the 7. Love my Birkenstock. No doubt this is my first of several Carhartt coats (I have a bit of a coat obsession, lol).
