My bed cracked completely but the heat pad held it together and i taped the top. I have about a 4 or 5 inch sweet spot i found that seems to be able to handle to keep going. I put in a warranty thing but dont think it will be covered but hoping they will give me a deal. My Alien is what did it. I use glue sticks on the glass and with having to use tape i might switch to that with the new bed. Its more work but things come off a bit easier. The pics are of the cracked bed the alien and my bearded man was done after the fact along with twist jar.
