I've been using alcohol markers since I was a kid, mainly prismacolor. But in recent years I've noticed their quality cheapening down, even to the point of finding them in Walmart!? They were always the "professional grade" to me growing up, but times change. And Copics are way too overpriced for what they are. It's a marketing gimmick.
I was surprised at how well Ohuhu markers are. I would say they aren't as fluid as prismacolors/copics, but the difference is so negligible that you won't notice unless you're a lifelong alcohol marker user like myself.
PROS: cheap, good quality, lots of color selection, easy to grip, comes with a carrying case
CONS: not as fluid (barely noticeable), cap colors don't match the actual pigment at all, unrefillable
If you're a hobbyist or looking to start getting into alcohol markers, I'd suggest starting out with these. Do your research too, there are plenty of video comparisons of Ohuhu vs other major brands.
