It is easy to sit there and giggle about Yihi making a better chip than Evolv. It is way easier to look at the mistakes of the trailblazer and do better than they did.
Just saying, yes evolv could have done better, they did blaze the trail here. The Chinese did not start anything, they got a patent for vaporizing nicotine. The ecig was patented here in the US in the 60s.
I'm sorry, but what trail did Evolv blaze?
They certainly weren't the first ones to produce a chip for regulating the power of mods. I think you'll find Provari and the Chinese Vamo were doing that 2 years before Evolv existed. I'm not sure who made the first commercial regulated mod or when it first hit the market, but there have been a variety of them since 2010 and Evolv didn't introduce their first chip until 2012.
And as for the ecig being patented in the US first, there was a device that was patented in the 1960s, but it's NOTHING like the modern ecigs we use today. The ecig as you know it was invented in China in the late 1990s and patented in 2003.
