    Lightweight but good quality

    Posted by Jerry on March 11, 2025

    It’s about the size of a water bottle and lightweight, making it easy for me to use. The delivery was fast. It arrived in just five days. I have some white spots on my forearms and fingers, so I’m starting treatment there first to see how it goes. Excited to track my progress!
