I finally graduated from ShuttlePro.
There are many reasons for this, but the main one is that the price is almost double what it used to be if you buy from a domestic mail order site. (It's cheaper to buy from a North American or British site and pay for shipping.)
This time in particular, while also coinciding with the last comic, Amazon only offers MakePlace, Rakuten has a mixture of items shipped overseas, etc. I thought, ‘Maybe it's time to give up on this equipment’ and searched for a new one.
I looked for a new one from a brand I've never heard of called SIKAI CASE.

The fact that the two dials are within reach was a deciding factor.
I found out after using it that the dials were the element I wanted the most, and now they fit in nicely.

For reference, here's the placement, etc.

The Shuttle Pro had to be soldered back on every time the tact switch on the button broke, but this one can use generic keycaps and axes, so it's good that it's easy to repair at a moment's notice.
I have not been able to graduate from Shuttle because of the drawback that once you get used to it, you can't use anything else because of the layout, but I would like to be able to move on to something with a row of keys in the future using this.
