I recently got a couple Vapeonly Aspire BDCCs, which I found to have a warm vape very similar to the Vivi Nova.
One of the Aspire sub-models happens to be called the Vivi Nova (e.g. Vapeonly - Aspire 3.5ml VIVI NOVA-S Glass BDCC Kit (Bottom Dual Coil Clearomizer)). So now there's the Vision Vivi Nova topcoil clearo and the Vapeonly Aspire Vivi Nova bottom dual coil clearo, plus all the VN knock-offs, and a lot of people new to vaping must be pulling their hair out trying to figure out the differences.
I wish the marketing people at these companies would pick up their game and start using less confusing names.
