If you order now, it will be shipped in 20 weeks, but I don't think there's anything to worry about since it's a company that won't go out of business.
It's a shame that it's not wireless,
of course the key issue is how comfortably you can scroll, but there are also projects like qmk wiggle toggle below, so I think it can be customized a bit.

I ordered it a while ago, so I think those who are interested should try it out.
