she’s been around for a few years and is pretty well known in this niche e.g. on the Twitter side but maybe hasn’t made it over here as much
some of her measuring videos have exaggerated labels (i.e. they’re not strictly in one go) but I’ve purchased this one and it seems legit to me at nearly 1800:

It takes her a long time to get it out and she goes off camera at some point but she’s already got 1700+ in the jug before then. And she’s got several powerful 1500ml pees.
