Why is the Air No. 2 Tripod Xianyu so cheap?

Because the second-hand depreciation of this product is relatively severe.

The effect of stabilizers varies greatly from version to version, so most people buy new ones rather than old ones, resulting in a very severe depreciation of second-hand stabilizers. There are roughly several types of camera stabilizers on Xianyu. Some review bloggers receive official new products for review, and then dispose of them second-hand after the review. A newbie bought a stabilizer in a daze and found that he didn't like it, so he disposed of it second-hand. Amateur sellers, who don’t know much about the products, just post sales information on the platform, and then earn commissions by going to designated store links. Professional merchants use their personal accounts to publish a large amount of post content, and the prices are indeed attractive. Regardless of the above, there are basically no big problems or pitfalls. If you encounter a pitfall, it can only be said to be bad luck.
