I bought that same gimbal, and it has worked well for me in the limited use to which I have put it. I have no experience with Wimberly or other more expensive brands, so I can't offer a comparison.
I will say I have used it less than I anticipated, because I find that with good technique, and thanks to VR and IBIS, I am able to hand hold my Z6/200-500 F5.6 more than I thought I'd be able to. No regrets about the purchase though!
I think that people suggesting that the OP should only buy a gimbal costing five times as much as the one you bought miss this point. The OP really has no idea whether he'll actually use the gimbal or not. These inexpensive gimbals are perfectly adequate for determining whether or not he'll use one. If he ends up using one once a year or so, it'll meet his needs. If he finds that it's a regular part of his shootiing kit, he will probably want to get a more expensive one. But I suspect that most gimbals, like most tripods, are purchased far more often than they are used. And, despite what afficionados may believe, that is not because the item is too low-quality. Not every piece of kit suits every shooter.
Exactly. Except the Wimberley is over 6x the price of this one, not just 5.
As a hobbyist I want to balance quality with cost. I chatted with my friend, PT Lee (look him up on Facebook - his portfolio of birds in Singapore and SE Asia is quite impressive) and he thinks the Wimberley is overpriced today for what it delivers.
I bought the K&F yesterday and will receive it tomorrow. I will put it through its paces and report back.
I will use this maybe 5x per year - hopefully more - so spending $600 is just more than I want to afford.
