“I've had this tank for about 2 months now. It has been a great product but take care of it. If the quartz barrier has survived a few drops the seal can break and start to leak. If it starts leaking it will leak like a mofo. The box comes with extra parts so you can always start out fresh again. Be very careful when unscrewing the quartz from the coil if you are using tools to get a grip. I've seen way to many people crack/shatter the quartz doing so. Otherwise. great tank. huge clouds and plenty of coils to choose from.”
