感覺好似幾好，但是不知道是否真的有作用！
Product Reviews
The duration to get PEMF results varies from person to person. Whether it takes long or short depends on the severity of problems and also the responsiveness of one's cells to PEMF. Some got improvements right after the first treatment while some took a month or more with continuous use, according to the feedbacks of our customers. By the way, one normally feels nothing during PEMF sessions, in case by "feeling" you meant sensation.
Thanks for the feedback. We suppose the insertion of the battery into the charger is what being referred to, which could be easily resolved by ensuring the battery terminals are properly connected to the charger, or simply do the charging with any other charger that is for 18650 batteries.
