Hi everyone! I wanted to share my experience with G-Pen Roam parts since my unit needed some replacements after a year of heavy use. The tank was the first thing I had to replace, which was pretty easy to do. Then the mouthpiece started getting clogged no matter how much I cleaned it. I was worried I'd have to buy a whole new unit, but my friend told me about a website with all the replacement parts. Open the page and you'll see they have everything from batteries to atomizers and glass tubes. The shipping was faster than I expected and the parts work just like the originals. It's saved me a lot of money compared to buying a brand new device. Just make sure you watch a tutorial before replacing anything yourself
