I've no idea what a piece of wire attached to a croc clip at one end and
a piece of rosewood (possibly containing silicon wafers?) connected to
the chassis of your Hi-Fi item is supposed to do. Presumably nothing as
they thoughtfully add the following caveat..

"Pls note : We can't 100% gurantee the Ground box have the expected
effect, because it is Subjective feelings，Different person, different
device, different condition and enviroment can let the respond
different, someone respond the ground box with great effect, another
person respond the box with little effect"

Makes 'running in' speaker cables seem positively sane!

In response to Brian's comments:

Audiophiles have always had a reputation for gullibility. As long as there is a demand for audio snake oil, there will be purveyors in abundance.

I mentioned earlier, in another thread, about a colleague of mine who ran a pro audio repair shop. When things were quiet, he used to make shielded mains cables (a braided shield connected at the Schuko connector only) with a clear plastic sleeeve over. Most impressive. Once the jigs were set up the cables were quick and very cheap to produce. He sold them for 50e to a dealer in Sweden whose customers mainly in the UK, paid UKP85, for a 2 metre cable. He was turning them out in impressive quantities. It came to an end when the dealer found a Chinese supplier who could supply a 1m50 cable for much less money. The retailer lowered his price to 75e and sales increased!!

I can't comment about Russ Andrews, but if you want to know about audio "smoke and mirrors" Brian, Magic Alex will interest you. He was the man who promised to build the Beatles a 72-track analogue multitrack recorder at a time when the 4 track Studer J37 was state of the art. He also said that he would render studio acoustic treatment, tiles, screens etc, as unnecessary by using an acoustic "force-field" generated by six massive computers which be bought as redundant technology from British Aerospace. Similarly, he claimed that a control to studio "talkback" system would no longer be required as he could electronically tune players/producers/engineers to the "same artistic wavelength". The Beatles put him in charge of their technical R+D at Apple Electronics to design and build there new studio in Saville Row. He brought them to to verge of bankcruptcy.

I met Magic Alex at a party at the Saville Rowe premises. He certainly had some "interesting" ideas.
