I have recently upgraded to the pro tank mini 3, mainly due to the fact that I dig the cinnamon flavors that tend to crack the plastic tanks. Overall I like the convenience of being able to replace the heads without much headache. The one thing about it is it is "airy" when you draw on it and I prefer some of the flavors don't taste as strong as with an iclear tank. I was looking for advice on any other glass tanks out there that might not have the same "airy-ness" and lack of taste. Thanks
