I found this cartomizer which fills via a drip tip setup and was wondering if anyone has used them, how they perform and how (easily) they fill.

The site says in the short blurb they can be filled 30 times or more. "Our company had newly developed out an Reusable Cartomizers with do not need to install the Cartridge. You can add the E- Liquid by the suction nozzle directly."

Does anyone have any first hand knowledge of these?
