I keep seeing this mentioned so I thought it would be good to ask here. What other chip manufacturer has offered firmware updates other than Yihi?
I own several of the M and J chips and have updated the chip two or three times, other Yihi chips as well.
The Evolv chip had three or four different releases of the same chip, no firmware updates and problems with most of their chips.
I own 3 dna devices but only use TL on the Yihi chips.
This may be a little devil's advocate-y, but I think Joyetech pioneered the concept (as well as the whole software-based interface idea) with the original eVic more than three years ago. Obviously, neither hit mass appeal back then...
