The product is very easy to assemble (battery not included). You can put in your bag when you go on vacation. Make sure you kown what you are buying. This is an Electrical Muscle Stimulation (EMS) with a foot mat not a regular massager. If you are looking for a foot massager please don't waste your time on reading the reviews. I sit all day in the office and don't exercise often, so i need something to boost my blood circulation for my legs.
After using it for about two weeks, my legs are not tight as before. Here is the simple instructions for you:
Step1. Put your feet on the mat
Step2. Press ON/INC (one time you will see red light show on #1, if not press it again)
Step3. Press PROGRAM to choose the mode you like (No matter how many times you press, it has 6 mode for you to choose. Choose the mode you feel like it, it doesn't matter at this moment. Once you get use to it, you can explore more)
Step 4. Press ON/INC again to start the simulation ( If you don't feel anything at this point, that means the intensity is not high enough for you, you can press ON/INC one more time to increase it. Don't press too many times when 1st using it because it might be too strong. I pressed it many times and it was too much for me in the beginning LoL)
I hope this will help the new users on how to start.
