The Tera is pretty awesome. I prefer using it with my water pipe but does work well with the mouthpiece. I prefer the plastic over the glass mouthpiece cause the glass does get hot. The only negative I have with the unit is that it does get pretty warm/slightly hot during the session. But other than that it’s great. Cleaning is easy with included brush. Just have to remember put screen back in after you empty the chamber. Only other vape I have to compare to is the G-pen which I don’t consider in the same category. But I love this vape.
