I doubt it is any good for that price. It is desirable to have a good, low price ergo keyboard, but not realistic. It seems to be aimed at people who want an ergonomic keyboard but don't want to pay for a real one. A real one would have R&D and quality switches, and together with a split, unique case design you can't bring that to market for $100 except if the product was made for low price instead of for best ergonomics. It is probably some stock switch for industrial appliances such as a control board. So what happens if you mount these on a keyboard and type for hours? I wouldn't be surprised if your fingers start hurting.
