No - they are independent and actually make their own [different from SMT] designs. But you need to compare closely as fundamentally they appear the same. Not surprisingly, Kayo say SMT 'copy' their designs, but with some shortcuts [and most probably, if you could speak with the manufacturer directly, SMT would say the same].
We investigated the SMT situation a while back and they swore black and blue that they were the actual manufacturer of the machine - not a distributor or agent, but the manufacturer. When we discovered this wasn't true we immediately lost faith and all interest in dealing with them.
From our limited experience, the closer you can get to the source with CN manufacturers, the more likely the outcome will 'remain' a success, because it's only when thing begin to go wrong that the relationship will be tested. At that point the agent/distributor has already made all the profit they're likely to make from you, whereas the manufacturer has their brand to protect and are most generally keen to receive genuine, positive feedback and suggestions. Just saying.
