It's just like this one, completely worthless, in which it allegedly worked by "electrostatic magnetic ion attraction," which translates to "pseudoscientific baloney" -- would be the nice word -- in which you string together a bunch of words that sound good, but it does absolutely nothing.
跟这个没两样, 都是一文不值的废物, 被说成是靠甚麽 "静电 离子吸力"操作, 若译作 "伪科学胡绉八扯" 就好了-- 将一些动听的词儿凑成一串 却什么功能也没有
