This cube is #1 istg. I bought it thinking I just wanted a cube like JPerm's since his algorithms seemed so smooth and quick and I also bought this cube because of the dark interior. Before I bought this cube I averaged around 26 seconds and after it arrived my average went down to 18 seconds. part of that is practice but a lot of it is just because this cube is absolutely godly. I strongly suggest people buy this cube.
One day I was making soup at 10:00 pm because I hadn't eaten all day. The soup was in the microwave for 6 minutes before I took it out and the container flexed enough for the soup to fall out of my hands and spill all over the counter and myself. My hands suffered severe burns and I couldn't cube for 2 days. but the soup got on the WR M 2021 and I thought it was ruined. I rinsed off the cube and set it on the counter so I could run cold water on my hand so it didn't get too bad and I thought the cube would turn like the original Rubik's Cube. NO! I dried it off and the thing was fast as lightning. it felt brand new!1! This cube has gone through so much yet it stands before me, right in front of my eyes as I write this. and the sticker stays on even if it's covered with hot soup for over a minute.
You can still see the burn on my left index finger in the video below but here's a quick 7:27 solve
