Our Promise to You

All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.

Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

i cant believe yj made this

Excellent

Ce cube est vraiment au top. A la sortie de boite il est trop relâché mais une fois resserré et bien lubrifié ce cube offre des performance incroyable. Hyper rapide et stable, la force des aimants est juste comme il faut. Il ressemble un peu au Hudong M, je les trouve un peu similaire dans leur comportements. il a sa touche personnelle on peu le reconnaitre entre mille. Très bon cube. il sera dans le top de 2025 c'est une certitude....

Very good cube

Definitely more than worth the money. The maglev is not too fast and the UV coating isn't slippery. It feels more like a zhanchi that has more stability but the flexibility of a Tengyun. It's not super quiet but is low pitched enough to not be annoying. The only thing I don't like about it are the center caps are kinda ugly. This cube imo is a better buy than the RS3M V5 BC. Both are great but I'd recommend the YJ Beta over that one.

It is really good. The Ferryoocore is better.

It is a good cube. If you have a large budget just get the Feryoocore and thank me later.

Great cube, some problems

For a midrange cube, the beta is very good. This is the best YJ 3x3 ever. However I’ve only had this cube for about 3 days, already have around 1,000 solves and the UV coating has already started flaking. I’ve had this happen on higher quality cubes such as my WRM V9 but that cube has over 13,000 solves and it just barely visible on a couple sides where the beta is flaking on almost every side. This cube has a super satisfying turning feel when set up, and I’ve gotten close to PB numbers in the limited time I’ve had to use it, however the quality control leaves a lot to be desired. YJ has introduced a new feeling as far as midrange priced cubes go, and as someone who’s used the RS3 v5 (in my opinion the main competitor in this price range) I prefer the softer plastic feeling and speed of this cube. But with quality I’ve seen so far, it makes it a tough recommendation.

cap fell off easily

a few weeks into using it, the corner piece started to fall off then not long after followed by caps of the corner piece completely fell off. Very annoying when you're trying to improve your speeed.

My son loves it

Bought for my son, who is not a pro, but turns that darn cube faster than my eyes can follow.  He is very satisfied with how it performs.  So, 5 stars, on his behalf :)

very good, breaking a little

After some time, a couple of months, the corner cap fell. very good performance and corner cutting. you need some lube, but it's not a must. If you go into a comp with it, sometimes the delegates might think it's a smart cube because of the holes in the center caps, so beware.
