mychway WL-UU1401 Owner's manual

Hello! I've reviewed the user manual for the MYCHWAY WL-UU1401 slimming product. This manual details how to use the device for treatments that combine radio frequency, ultrasonic cavitation, and laser technology for fat reduction. I am ready to answer your questions based on the information provided in the document.
How many treatments will I need to see the results?

Can I have more than one area treated at one time?

Will the inches stay off after a treatment?

Does the treatment hurt?
