The LanLan 2x2x2 is basically a Eastsheen 2x2x2 with a screw-spring mechanism. It is manufactured by the LanLan company in China. These cubes are very smooth and can cut corners very well. I did the R U R' U' x6 thing on the Eastsheen, then on the LanLan. My times improved up to 30%. I also have broken my 2x2x2 record just twp days after I got my LanLan. I really like the LanLan 2x2x2. You can get them from popbuying.com, I think, for 4 bucks. They're even less if you get these in China. I mean, you could by lunch for $4 or more.
Overall, I am highly impressed with this cube. I'd rate it a 98 out of 100. For my Eastsheen 2x2x2, I'd rate it 91 out of 100 because it cannot cut corners.
The LanLan 2x2x2 does not have 100/100 because the LanLan company uses this unknown lubricant to lube cubes, but that isn't a big issue so it got 2 points off.
The Eastsheen is 9 points away from full score because it cannot cut corners really well.
