Which brand of transcranial magnetic stimulator for home use is good

Transcranial magnetic stimulator for home use, there will be a lot of brands on the market now, mixed. Unable to determine whether effective, because of large medical equipment, hospitals use a very strong field of transcranial magnetic stimulation, than the nuclear magnetic *** vibration of the field strength of the low half, the general nuclear magnetic *** vibration is 1.5T, while the transcranial magnetic stimulation is 0.8T. Only in the strong field strength, it is possible to play a very good therapeutic effect. Home use may be less than 1% of the medical equipment. So it is difficult to penetrate through the skull and act on the surface of the cerebral cortex. Some patients want to do every day, non-stop, every day stimulation will not have a little efficacy, it can be said that the home equipment is almost no clinical trials after the hospital test, there is no large-scale patients to verify. So what degree of efficacy in the end can be achieved there is no scientific figures. So if you only listen to simple manufacturers publicity, it is likely to go to buy equipment, and these devices are not cheap, but the cost-effective is not too high.
