Does anyone have actual experience with Mighty Max batteries?

[Allen42]

I'm assuming my 2019 RTL has the original battery, so want to replace it. (I sent an email to yuasa to translate the date code for me.) I'm finding most replacements are $120-250, but there are Mighty Max batteries with the same specs for $55-70! They seem to make a both regular and gel type.

Does anyone know anything about these? (And please, no generic "you get what you pay for" type of advice without practical experience ... I would like real world knowledge about this brand. Which, to be fair, may be worth what they're priced at. Or perhaps I've found a hidden gem?)
