The Ergo pro is an excellent keyboard. I’ve had two. Biggest problems are reliability - my first had a bunch of keys stop working in 9 months! They sent a replacement half for $99. That one stopped working 13 months later.
I would google around and read some reviews on Amazon and Reddit before committing. Sadly these issues seem common.
Their warranty support was… not good. Their COO didn’t really stand by their product. I know 4 other people who had similar experiences - they all love the keyboard but switched after it basically fell apart.
I’d buy another in a heartbeat if I knew it would last well beyond the warranty like every single other keyboard I’ve ever had over 32 years of computer ownership.
That sucks. Before buying, I read a lot of reports of key-repeating issues, but hopefully that will never be an issue for me because 1) I buy the 'Low Force edition' which uses different switches to the normal one, and 2) I spoke to a distributor and they told me it was pretty easy to fix that particular issue by cleaning the mechanism. Though I do actually have some New-in-Box spares that I snagged for really cheap, as an insurance policy!

I've already settled on my "endgame" desktop keyboard in the Matias Ergo Pro though. Don't like layouts that stray too far from ANSI.
