You have every right to your opinions, but other companies charge extra for extension tubes or caps. Why hate on Provape for doing the same? Provape has defended their additional charges for the custom paint colors because it is done by an outside source which they have to pay for, it is not done in-house.
The blue and green LED screens also cost Provape more money in parts to make themselves, so the additional cost is passed on to those customers who choose those colors. Same with the carokote paint finishes.
Why charge all customers an higher base cost if they would rather have the original silver finish or original red LED? I see Provape's pricing decisions as a way to keep the cost of a basic Provari to be more easily within reach of those customers who choose to just get the basic model. If you want something with a little more flair or the ability to choose longer battery life (which not everyone wants), you'll need to pay a little more.
