I purchased this one a few weeks ago on Amazon, and it's been my go-to 2x2 ever since. I've likely put a few hundred solves through it.
First, it's a Cyclone Boys cube -- you're going to get a glossy, smooth stickerless cube with unusually deep and rich colors. (They still use the popular fluorescent yellow, though, which can be tricky to distinguish from white in dim amber-tinted home lighting.) The faces are slick and highly polished, which may give some folks grip trouble -- I've had no problems yet, but it's definitely not the textured, grippy stickerless surface you'd get from a premium stickerless cube, and that may be a problem for you. Turning will be a bit loud and clacky, but I note that the smooth surfaces make for particularly good flicking, and the cube seems to know when to stop after a quarter-turn, despite being non-magnetic. I'm not a flicker, but I can reliably tap a corner firmly and set off a controlled turn that lands where it's supposed to land...and given that I'm wrestling with some nerve damage in my hands, this is unusual. Corner cutting is surprisingly good for a budget cube, too; I manage 45-degree cuts reliably, and the cube feels quite content under pressure to turn a side, out of alignment.
I stand by Cyclone Boys' cubes as a decent budget choice, provided you're comfortable with the caveats. You'll be dealing with glossy-smooth faces (and may find these slick and tricky to grip, especially if your hands sweat), and you'll be dealing with loud, clacky turning. (This may be treatable with lube, but I've never lubricated mine, so I can't offer any thoughts from experience there.) If these aren't a dealbreaker for you, then I suspect you'll like Cyclone Boys' characteristic take on smooth, controlled turning...or at least, you'll like the low price point of trying them out. They have a unique feel, slick, glidey, clacky but not cumbersome...it's not for every turning style, but it's a compelling one, and definitely attractive to some cubers. (I'm one of them.)
Rather than suggest that the FeiChang is the best 2x2, I'll suggest instead that the FeiChang is a really good example of the Cyclone Boys cube's strengths, and a great way to discover what makes Cyclone Boys' cubes unique. If you're not going to like the slick, glossy faces, I imagine that you're most likely to be able to deal with them in a 2x2, rather than a 3x3 (or higher), as you have fewer cube elements to steady or isolate when rapidly turning. If you're going to discover that you don't like Cyclone Boys cubes, I suspect this is the one you'd dislike the least, simply for its larger cubies scale and ease of stabilizing the non-turning elements.
You'll either love or hate Cyclone Boys cubes. They're unusual, they're a bit polarizing, and they're not for everyone. But if you're curious, if you think you might like them...the FeiChang is a great introduction, and a solidly good little budget 2x2, besides.
