The Hays7 is Yuxin's newest 7x7, made in collaboration with world-renowned big cube solver, Kevin Hays. The Hays7 is famous for setting multiple continental and world records, most notably Kevin Hays' 1:59.95 single (the first ever sub 2 official solve) and Max Park's current world record single of 1:47.89. The Hays7 has a smooth and compact feel, making it possible to push your TPS more than ever on a big cube.
The M version comes factory magnetized.

This is by far the one the best 7x7's I have ever had the pleasure of using. It took a few solves to break in and I put a little lubical silk on to smooth it out, but it turned incredibly freely and I barely had any catching and no pops. The magnets in the middle layes keep rows in line and makes doing those wide M slices much quicker and easier. The cube exceeded my expectations and definitely one I would recommend to anyone looking for a quality magnetic 7x7
This is the best 7x7 I ahve ever felt. The cube fits in my hands, and there is not mush too say but it’s very good. Yes.
This is an incredible cube. So fast and smooth but still able to be controlled. So happy I bought this cube over the spark. I don't even need to try the spark to know this one is better. If you already have a spark this isn't necessary but it's certainly an upgrade still.
I adore this cube! i got it in June but it still blows me away! i love how i just want to pick it up and cube. my only complaint is that the caps on the pieces fall off mine. and the corner pieces are getting out of the socket of the cube, making them stick out. i love the cube! i just wish it would stay together a little better.
This puzzle is amazing, magnets are of the perfect strength, I just wish that the outer layers were stronger. With the many solve I have done with this puzzle, it had only locked up a few times. This cube has made 7x7 much more enjoyable for me and I liked the small size. I can speedsolve on this and not worry about lock-ups or pops. I would highly recommend this cube to anyone who is looking to get faster at 7x7.
I had been using the Hays 7 as my main cube from november of 2018 to january 2018 and have been immensely enjoying it over non magnetic 7x7s. everything everyone says about how good this cube turns and corner cuts is totally accurate. My main gripes is that the magnets on the outter layers seem to be weaker on this cube than the xman spark (which I get better times on) and the caps on random center pieces fall off the cube and need to be superglued back on at times. Ive had this happen with 5 different center pieces and this is simply not a problem that the xman spark has. I would say that the hays 7x7 stands apart from other 7x7s for its plush feel when turning and weaker magnets in the outter layers.
Prior to this cube, I was using the WuJi for nearly 2 whole years and it had an extreme sluggishness, lockiness, and stiffness which makes 7x7 uncomfortable for me to do. The Hays 7 changes everything. Out of the box, the cube is very loose and sandy, but it gets better with some maintenance of the cube by lubing the core with weight 5 to prevent plastic dust in the workings (due to friction), DNM to maintain the raw speed, and tightening the tensions to prevent lockups. After the setup, the cube has a very fast turning with a moderate flex to it and a satisfying feel. Magnet strength in the cube is strong to weak from inner 3 layers to the outer layer. This cube is very stable even though it's flexible but, that does not mean that it's an end of an era of lockups. I've experienced jumbling due to rough turning. Because of this cube, I now averaged 4:10-4:20 with a PB of 3:43. Overall I recommend this cube if you like fast 7x7 and flexiness. Also, thanks to Kevin Hays (favorite cuber) and YuXin for designing this cube to be this good.
Prior to the Hays 7, I've been using the stock non-magnetic WuJi for nearly 2 years. I am happy to say that I finally made a decision to upgrade my hardware. Let me give you the reason why the Hays 7 is miles ahead of the WuJi.
Out of the box, this cube has a fast, buttery smooth turning with sandiness as expected with newly unboxed cubes. When I did some turns on it, it is quite loose which causes to have slight lockups. After tensioning the cube and breaking in without any setup, it is my main. Breaking in causes this cube to have a fast, airy, and buttery smooth feeling with a very good amount of flex. That flex helps my increase my TPS by a lot. Compared to the WuJi, it is really sluggish and very catchy with really bad lockups. Its lockup is very catastrophic that if you fix it too harshly, one of the pieces will snap which is why I couldn't do 7x7 very much. With the Hays, my average dropped nearly 40 seconds from 4:45 to 4:15-4:26 average and I managed to get my first sub 4 single, 3:59.60 thanks to its good performance. If you are serious about 7x7, get this. Also, thanks to my favorite cuber, Kevin Hays and Yuxin for designing this 7x7 to be this good.
This is the best 7x7 ever made.Out of the box it was very nice and smooth to turn with that YuXin feel.The tensions were pretty even and tight. After lubricating the pieces with weight 4 and Weight 1 with some Compound X.It became one of the smoothest puzzles in my collection.A definite upgrade from the WuJi M
which was very expensive to get a magnetic variant. Definite Buy!
out of the box, the feeling feels quite nice, although solving on it was a disappointment, I was slower on this than my wuji ( my previous main ) after set up and break in it felt smooth and fluid. Now I average 30 seconds faster on this cube now
