Well the Novo 2 was $20 from Element Vapes, so didn't cost much to try. The shape is ideal, and they got rid of the nasty stinky glue smell the Novo 1 suffered from. MTL is still not ideal, but if you hold fingers over the air intakes, it's a bit better.
I have no idea if it will last. The Novo 1 is still working, but I am only expecting 6 months of use from either device. Still cheaper than 3 packs of ciggies for $20 that lasted me 1.5 days.
