If the Chinese units are the same quality, engineering, and materials, then no issue, but the ones I have seen are not as well made as the name brands, at least not to the eye. The welds are not as good and I wonder about the quality of the steel, balancing of flywheel, bearings, etc -- stuff you can't tell by eye. A well made Chinese product can be fine, but that's often hard to know/verify. So I'd say to at least go with an importer that other people have bought from, and hopefully it's a company that has parts/support.
Woodmaxx improved the TH-8M based on Jimma WC8 years ago, Victory improved something else more. They are manufactuered in different factories which located in two different cities next to each other, they are the top quality level compare with nearly another 10 factories who produce same chipper in China. I visited most of them these years.
So it's fine no matter you choose woodmaxx or Victory.
It's difficult for US people to identify Chinese attachments through internet information, but it is always good to spend more time and dig more into internet.
It's better to deal with Chinese manufacturer or US importer, the basical rule is that the closer you reach to who produce it, the more support you will get.
Both Woodmaxx and Victory are importer.
Interesting information. Thanks! Why did you visit the factories?
In this day and age it's really hard to tell. I'm buying a wood lathe from Grizzly. Grizzly is just an importer who buys them from a couple of different companies in China and Taiwan. A quick search for the actual company that makes it, in my case the Burt Group, you find they have the same equipment listed, just a different color. If you wanted to buy 10 of them they would sell to you. These same companies make equipment for much larger names as well. What is harder to tell is if the importer, in my case Grizzly, specifies specific brands of bearings or the castings to be finished to a specific level. I'm sure Harbor Freight is the same way, they just have lower standards so they can sell cheaper. So when it comes to quality it just comes down to what the importer specifies.
