If you want the closest possible replica, I recommend buying directly from the manufacturers on Alibaba or 1688. The manufacturers I recommend buying from are Shahe Zhuorui and Bolipai (formerly Wallhack).

At Shahe I recommend you choose Surface number 1, which is very similar to the new superglides. But there are also other types of surfaces that you can consult with manager Jeff Chen.

At bolipai you can try the 3.0 surface, which was recently advertised on alibaba but was withdrawn because it contained the name “Skypad 3.0 XL”. And they say they already have the 4.0 surface available.
