Supports my Blue Yeti Nano no problems, wouldn't have a problem holding up a full size Yeti either. The included bracket does NOT fit USB microphones by default, which is why it says incompatible, but while using the adaptor included with your yeti, it will fit perfectly.
The springs are quite firm, perhaps too firm, as if the boom is set at full extension, it does actually retract very very slowly, but this isn't noticeable for quite some time. This is only at full extension however, otherwise it's very sturdy and still.
The springs are also quite loud as they "twang" over one another, so moving the boom while broadcasting isn't a good idea. The included pop filter seems to be of good quality, and does indeed block SOME wind, but not all of it. It's no game-changer, but it does it's job well enough. Bear in mind it's quite large which helps its purpose but not the aesthetic.
The stand picks up a LOT of vibration and noise from your desk, so if possible isolate the boom entirely from your desk. I have mine mounted to a tall shelf next to my desk which works perfectly, although I need the boom at full extension, meaning I get the slow retraction problem.
The way it bends when it folds up makes it impossible to mount this to the back of your desk if you're against a wall, which is something to think about.
It has no cable management included (zip ties, velcro etc) so you'll have to route your mic cable around the scissor which causes problems with folding it up fully (a non issue for me because the shelf it's on doesn't allow for that anyway). Some (very) small 3M sticky hooks would do you a world of difference here.
Overall it does the job fine, and with nothing "professional" to compare it to, I can't tell if it's a great deal or a dud. To your own discretion but for my use case, it's perfect and 100% worth the (cheap) money. The folding mechanism is tight, the screws work well to tighten it in place, the desk mount is secure and sturdy, but if you choose to use this attached directly to your desk, invest in a GOOD shock mount. Nothing cheap though, don't cut this corner because you WILL regret it. I'd recommend this to a friend, bearing in mind the cons, but at this price point, I can't complain.
