I've been tempted to get a couple. They're not going to be as thick as the fly high bags and will likely use older style fittings. But for the price, I don't think they're garbage
I have some. Exact same as the sumo bags. Same fittings. Same quick release quick connect. Accepts the same sumo pump. I have sumo bags also and if you don't look at the name you can't tell the difference.
