Is it Good?
I've seen both praises and nah comments. Some find this to be the ultimate trackball. While others, finding the shape not for their hands.
I've seen simliar remarks on other popular trackballs.
With trackballs, you really have to see for yourself which is best, for you.

Elecom HUGE vs Logitech MX Ergo
A review by Takom, 2020-06-16.
So anyways, my Elecom HUGE is here and it's more like, large-ish than huge.

The back part is padded, so it's like a wristrest. Buuut. Taking that into account, it's actually too small for my hand in the position it's meant to be used in. That's certainly the biggest surprise. Very pretty to look at though. Thumb position is not quite as comfortable as I had hoped either. Might use it with a thumb cast, lmao. Switches are good, but especially the forward/backwards switches are very stiff.

so thus far, and to my surprise (I really thought I would like the HUGE more), the Logitech MX Ergo comes out on top for me, easily.
actually I have a sore thumb too but my thumb ball exacerbates it much less than than a mouse or the HUGE's thumb buttons.

as a collection piece though, eh, it's pretty good. I find the most comfortable way to operate it is the same way you would operate a Logitech Trackman Marble , oddly enough
