In term of vapor comparing to the original glass It is better and smooth without any water coming up. My only - would be that it is a bit Diagonal / and mine tilted with some strong wind coming out the windows and fell out the table and broke, so I would recommend You use a stabilizing base if you choose to get this 1 cause its is a bit shaky, I just got the original glass replacement from JCVAP and from early use it is perfect fit and smooth so I would recommend you get that one but its a question of choice.
