Received my Yoobao Apple-style case today. It's described on the packaging as "Yoobao Lively Case".
The good: It's a precise clone of the Apple case, so all the things that are good about that case — the basic design, the typing angle, the lack of added bulk — are replicated in this one. Plus, the material it is made of (obviously PU leather, aka "pleather", rather than genuine leather) has none of the fingerprint, dust and dirt magnetic properties of the Apple case. If you want the Apple case, minus the crud, this is the one to get.
The bad: The pleather feels cheap. It's nowhere near as good quality as the faux leather of the V3, and there's no way anyone would mistake it for real leather.
The ugly: It has the slightly off-putting smell others have reported with (some) versions of the V3/Magic case — hopefully this will diminish over time (indeed, a quick run with 303 Protectant seems to have tamed the worst of the pong already).
Bottom line, at twenty quid it's cheaper than the Apple case and easier to live with aesthetically. If you're sick of having to clean the Apple case daily, but prefer the basic design to any other case (as I do), give it a go.
