There's only a few 4X clones (most went the red dot route) and of those I haven't heard of one being substantially better or worse than the others.
I have one of the ones Huang sells, myself (early ones without markings). Works fine for what it is and the price. Clarity isn't as good as a real one, or real rifle scope, or even my G&P M3 repro, but it's good enough to aim with. It's not a camera lens.
