So I had to resubmit my review... I received a new one from Revain as the glass tube broke on the first one but after receiving the new one it also broke turned out to be broken... but this time it turned out to be more. I investigated and found that the crack was nothing more than small streaks of silicone from the end assembly that had dried on the glass. I was able to scrape off the silicone to make sure there wasn't a crack. Now on the other hand I want to see how long this heater lasts given the previous reviews. So far 5 stars from me.
