Lei Jun also forwarded the news that Xiaomi Wiha 8-in-1 ratchet screwdriver was on sale, and promised that: "I will buy one first if the Xiaomi 9 series can't supply more than one million units in the first month, I will go to the factory to turn the screw immediately!!! Next Tuesday, let's see our stock.”

The Xiaomi Mijia Wiha 8-in-1 ratchet screwdriver adopts WIHA patented design and unique production technology. It has won the German iF Industrial Design Award. The three-level ratchet can be adjusted freely without changing the grip position repeatedly. It can rotate unidirectionally and continuously. It can also be fixed and not rotated. The torque value reaches 15N/m. It is labor-saving and efficient.

The screwdriver is equipped with 8 pieces of S2 high hardness WIHA batches with hardness up to 60HRC and double anti-rust treatment, which is more suitable for Chinese families. At the same time, the screwdriver is designed with hidden warehouse inside, and the batch can be used as needed to reduce the risk of loss.

In addition, the Xiaomi WIHA 8-in-1 ratchet screwdriver is equipped with a 105mm extension rod to support narrow space operation and wider use. The extension rod can be disassembled, occupies less space, and is convenient to receive and carry.

The screwdriver grip is ergonomically 8-edged. The octagonal cross section fits the stress surface formed by thumb and forefinger and tiger mouth, so that the tool fits the hand to a greater extent, which is conducive to power transmission.

At present, the Xiaomi 8-in-one ratchet screwdriver is priced at 99 CNY (about $15) in China.
