Models of quasi-periodic oscillation (QPOs) based on the assumption that QPOs have magnetospheres are discussed. Evidence supporting the use of magnetospheric models is presented. The study of low frequency noise in the blob model is examined, stressing the question of the how much the blob-to-blob correlation is needed to suppress the low frequency noise to the levels observed in QPO sources. It is suggested that in low mass X-ray binaries, larger amounts of energy should be expected to be released at the magnetospheric boundary rather than on the neutron stellar surface. Also, examples of reproducing hardness ratio curves and QPO frequencies are given.
