Only left thumb was missing a socket, but service/advice was good

It took a little over a month for the goods to arrive after I sent payment. I was surprised at how big the cardboard box was.

I ordered all switches assembled, but three switches for left thumb were missing sockets.
I asked a question on the homepage and received a quick response.
When I asked what to do, I was shown how to open the lid and solder the sockets myself.
When I asked if I didn't know how to open the lid, he sent me a clear photo. Not only did they show me how to open it, but they also gave me sufficient instructions on where to solder.
There was nothing difficult to understand, and I was able to soldered sockets and use the finished product.

I was advised to return the entire product, but I wanted to use it so I handled it myself.

It was my first time using a three-dimensional keyboard, so it was difficult to use, but I think I'll get used to it.
I immediately realized that it would make it easier to use my thumbs.

Unconventional, yet exceptionally comfortable

As a person switching from the most generic keyboard one can imagine ( staggered + full size ) it was pretty interesting yet a bit challenging idea to switch to such unconventional design of keyboard, it takes time to switch ( especcialy if you switching not from splits ), but it is much more convinient than it looks like, most of buttons are where u expect them, and ability to use not one, but six different buttons with two fingers you ussualy use just for Space bar, is so convinient and easy that after trying you feel betrayed that on most regular keyboards so much space is used by one key.
Ability to modify the keyboard both in software ( qmk, vial... ) and hardware ( changing the looks of case and printing it in any color you want to ) is what is also great.
The only problem for now is mostly lack of more detailed and packed documentation about assembly of the keyboard, but the creator of it always happy to assist in discord so its not a big deal, at least for me.
