I've been really happy with this one. I've heard bad things about the one you selected. https://www.amazon.com/MAYFLASH-Converter-Compatible-Nintendo-Monitor-Supports/dp/B07XG6X4TC/ref=mp_s_a_1_3?crid=3C2AZCP2G72FI&keywords=mayflash+wii+hdmi&qid=1646997845&sprefix=mayflash+wi%2Caps%2C273&sr=8-3
Wii2HDMI have 2 or 3 revisions, one of which is good, the others... While not as bad as composite, they are worse than component, IMHO. The issue is that they all share the same box, case and model number, afaik. There is an adapter from mayflash, its sold out everywhere I look in, but looks promising, per amazon reviews: https://www.amazon.com/-/es/dp/B07XG6X4TC?currency=USD&language=en_US

The Mayflash HDMI adapter is the way to go. Otherwise the Electron Shepherd Analog2HDMI chip is excellent, but requires a bit of soldering.
My Wii2HDMI had the wave pattern and completely died after a month. The Mayflash adapter is as crisp as component was on my old TV.
Wii2hdmi should also enlist 2other manufactory one of them is
