one of many "far east" manufacturers and marketers.
The "dirty little secret" is that folks like these make a lot of the gear and gear components that are used in various branded products.
Just like the state of electronics years ago, some of their stuff is a real stinker. But also like that industry, the far east folks learn fast, and there is a very real possibility that in a few years they will be making the best gear available in the marketplace for a price that can't be touched by the "US" or "EU" manufacturers.
Right now my biggest concern would be a supply of service parts, as many dealers will be loathe to work on these things, simply because they cut into their "locked up" market. So you may need to be able to source parts, and so far, IST is not supplying them to the open consumer marketplace. I have talked to them about this, but there is a significant language problem, and the US offices are somewhat detached from their manufacturing and policy-making folks over in the far east..... pretty typical for a company HQd over there.
