I purchased this cube as a desktop calendar, and it is a clear, attractive, useful cube, with a couple fixable flaws.
First, it is pretty tight and scratchy out of the box, which is easily fixable by loosening each side a full turn and a few drops of martian/lunar on each of the slices. After this, the cube moves rather well. Mind you, it is not a speedcube, and I didn't expect it to be, so it's movement is good for a calendar 4x4.
Second, as was noted by a user on the Discord server, the only "5" on the 3rd row is on the same side piece opposite "R", meaning MAR 2025 and APR 2025 can't be selected as currently setup. (This can actually be seen in the photos of the product.) Similarly, the "6" and "L" are on the same side piece, preventing JUL 2026 can't be selected next year. However, the cubies are a split-piece design that are easily separable, and it was easy enough (after loosening the cube) to remove the "5"/"R" cubie, separate the cubie halves, and recombine them individually with another cubie that had two blanks. There is another dual blank cubie in the third row that will allow the same correction for the "6"/"L" cubie. There seem to be enough blanks throughout the cube that reassinging these two blank cubies shouldn't affect any dates going forward. (counted 19 third row blanks, where at most only four should be needed for any future date).
I've owned a stickered 3x3 calendar cube for almost 10 years, but the stickers have been "starting" to peel for several. I really appreciate the printed-on. Hopefully they don't wear off too quickly. Although the screening process does leave some of the pieces pinkish/reddish (from overspray? rubbing?) it doesn't distract too much.
Overall, I am happy with this cube and would recommend it to any cuber that works in an office environment.
