Indeed, perhaps it is due to the quality elements that have been used, its durability can be quite high, it is the best there is technically, about $40 or $50, would have been a perfect price.
It could be said that its real price is quite low, but due to shipping and other aspects to the rest of the world, it is inevitable that it will go up by 30 or 40$ for the long journeys. When it becomes more widespread, the cost will surely go down, I'm sure I can find it at the time in about 50~60$.
