Why is Finger Spinner so popular?

​Why is it so hot? Personally think that the main features:

1, the finger is a very portable gyro is very compact portable products, the majority of the material is titanium, bronze, weight is generally in the 50 - 80G, carry has become the most important feature of it, to be known as the EDC portable, but he the most important factor for success of.
The law allows 2, I think it is the most harmonious all the products in the EDC, whether it is a knife, a flashlight, this product is not harmonious, although in the United States is a knife can buy a portable, but not every place is also a flashlight.
3, no functional functional products must be available products, product release in MD engineering company, a lot of users, it can be used to reduce anxiety, hyperactivity, and even boring can help smokers say they quit smoking, but whether or not the basis, but today the development of this way has been proved.
4, long period, need to be big, high prices in the United States EDC ring finger gyro fire, and make this kind of products are manual knife makers or designer, each a product design need to go through a lot of time to design, grinding, installation, and the number of each batch is also very small, generally 15 - 30. Rarity is perhaps the truth.

5, businesses speculation Torqbar first batch of products, the official website price of $139, when the product in the United States, the secondary price has been fired to $300 + can not buy the point, the custom version is more like not to think about. And to the domestic, there are businesses together, do not sell, deliberately raise prices.
