Problems with the new coils

Dear Sirs

I am using a Aspire ET-S BDC, combined with a Vision Spinner 2 battery. For the first couple of months everything worked perfectly. Now I received the new coils and suddenly the product doesn't work to my satisfaction anymore. There is too much drag (not enough resistance) and, even worse, there is liquid in the chamber which makes this gurgling sound and sometimes droplets of the liquid spray into to the mouth.

The new coils are from a box with the labelling "BVC Clearomizer Replacement Coil". The old ones used to have a slit on the bottom, the new ones don't.

Am I using the wrong coils or is there another problem?

Thank you for your feedback.

Kind regards
