Mad God is a company specializing in the production of sporting goods. Compared to other brands, the durability of the Mad God wrist force device is excellent. Electrochrome plating springs are used, which are not easy to break and deform. The high-strength solid frame results in excellent overall durability. At the same time, it supports force adjustment, but it must be achieved by moving the sponge in the middle, which is not very convenient. The price is slightly more expensive, 49 yuan, which is suitable for ordinary users.
