It looks nice and does it job well but there is a little problem, it doesn't fit well into my kanger mow tank. Its loose will easily pop off so you'll have to be careful otherwise you might lose it or break it if it falls. It appears it might just be an issue with the o-ring however and could be fixed. I already was able to slip an additional o-ring from an ego tip below the o-ring on it for a nice tight fit, but it sits a little crooked that way. Otherwise I still like it and it might fit on a different tank better.
