W_ denies MOVs are commonly used in typical electonics or modern
appliances too. He had to, because he can't answer the obvious
question of how MOVs can be used effectively in these applications,
yet they can't work in plug-in protectors and the only way to get any
protection is to have a nearby direct earth ground. Faced with the
problem of MOVs providing protection in electronics/appliance without
an earthground, he simply denies MOVs are used in electronics and
appliances. ...

Using trader's reasoning, all appliances contain MOVs. Therefore
plug-in protectors need not be purchased AND all appliances never
suffer surge damage. Conclusions directly from trader's post.

Reality: all appliances contain protection using numerous techniques
such as galvanic isolation. Protection that means all but a rare and
typically destructive surge is made irrelevant. Internal appliance
protection is dependent on a properly earthed 'whole house'
protector. The typically destructive surge must be earthed to not
overwhelm protection inside all appliances.
