(sorry) What is the maximum number of PEMFs that can be run at one time? I would like to try this in a holographic sticker and run all four at once to save time, but if it is not as affective to run more than three at once, then I will need to do it differently.
（抱歉）一次最多可以運行多少個 PEMF？我想在全息貼紙中嘗試這一點，並一次運行所有四個以節省時間，但如果一次運行三個以上沒有那麼有效，那麼我將需要採取不同的做法。
