I love my new EGO W but both tanks have started cracking and leaking. The tanks are made of a clear thin hard plastic and contain the atomizer and a wick. I can live with these tanks until they get the problem resolved. At this point the EGO T looks like a better choice since the tanks are just tanks. My EGO W came with a hypodermic for loading but there is a tiny cap that has to be removed and replaced after filling. For those not familiar with hypos, they must be loaded from the plunger side since they cannot draw up the juice. It then takes a substantial pressure to get the juice into the tank. I am thinking I will get an EGO T or see if the parts are interchangeable.
