So I bought the Veicomtech detox machine for my feet and I love it! Some key thoughts to remember is, It's requiring sea salt, so they give you a spoon to measure out. You measure out 3 spoonfuls of sea salt and place it in a hot water. Second of all the wrist band can be adjusted to your wrist. Add lotion on the inside of your wrist. Or use a wet paper towel. This will cause a connectivity. 3rd of all, The array, has to be submerged almost up to the top of it in order for the bubbles to emit. If you use too much salt or not enough salt , the array is not submerged or the wrist band is loose or has no connectivity ,due no lotion, the machine will cause for an error. Read how to put each item in its proper place. Enjoy! My second use and no problems! They do offer insurance, so invest! They do offer bags because this is gross to clean ?!!! If not soap and water! Don't forget to mention this to you GP if you have any medical issues, because it pulls toxins and much more through your feet. Oh, also comes with a waist band. Have not tried it yet! One more thing Amazon sells Cell power, this replenishes the nutrients and Oxygen to your cells. When I professionally had this done, they gave this to me, before and after treatment in small cup of water. Peace and Blessings!
