Evolve will sell chips for what they want. Wholesale pricing is wholesale pricing. Then you have a premium top of the line chip, and there is no point to going full retard and giving them away. You mark them up as usual and make profit.
Hcigar is cheap, but good. They are trying to get a better name. MAP pricing for a VT200 is $170. I bought mine for $90. No warrantee for breaking MAP pricing. I don't care for that price. WISMEC is not doing anything special, and they are not giving them away. Sigelei has a good name. They are not doing anything special, and they are not giving them away.
The Vero has been out for a while and it is triple 18650. It's not new. Several other custom 3/18650s out there. For the size of 3/18650 you can have a lighter lipo with higher capacity and none of the limitations. This isn't ground breaking.
Bottom line is Evolve is at the top of the heap right now. Yihi is playing catch up. Everyone else is a step behind. A metric shit ton of budget cut rate makers out there. It's a hard market to dominate. There is no market for high end budget gear. You either keep your profit margin at the top, or you jump in the swamp. No money in doing both.
