【Height Adjustment Function】 With its unique idea, the FREAK, which is the only one in the world that can freely change its height, provides a custom-made FREAK-like feel to fit the user's hand. Just as you can finely adjust sensitivity, dead zones, etc. in the game settings, the height can also be adjusted in 0.1mm increments, making it a one-of-a-kind FREAK that you can adjust to fit your hand and expect to improve your aiming ability. 【The Lowest and Highest FREAK in the World】 Unlike large FREAKs designed for the size of foreign hands, this product has a size that matches the average Japanese hand size. Therefore, the world's lowest FREAK height is available in the lineup. Also, if you prefer a higher FREAK, you can order the separately sold BASEPACK, which extends it by an additional 2.1mm, making it the highest FREAK in the world. 【Made in Japan】 The highly technical Pro FREAK can only be manufactured in domestic factories. In addition, these products have obtained a patent (Patent No. 6797507) and have a unique function in the world. Pro FREAK is of high quality, and the estimated lifespan is over 4 years. It is manufactured with a specially formulated elastomer material to prevent the rubber from hydrolyzing and deteriorating in the high temperature and humidity of Japan, and it will not tear or become sticky even after many years of use.
