I have had 3 aspire nautilus and have had no problems with them. I ordered an atlantis last week and got it in about 3 days ago and it doesn't work at all. I think the problem is the metal tip that makes the connection from the battery to the coil is not coming into contact with the battery. I have 2 batteries by other companies and 2 of the aspire vv batteries. I have tried all of these with the atlantis and it does nothing.
