Type E cubes are known as Diansheng (or DS) cubes. Out of the box they are quite bad, but after lubing with silicone they become much better. One problem is that they are somewhat prone to locking up, due to the very cubic cubies. There are two types of DS cubes, no.222 and no.333. Rather than stickers, the Diansheng no.333 has the colors painted onto the sides of the cube. The color scheme is a mirrored version of the Western color scheme. The no.222 has regular stickers. Both of the painted and stickered types have different cubies. Because of their very light weight, and very loose, smooth turning; DS 3x3x3's are often used in One-Handed cubing.
