I'm not sure what the general consensus on the QYT KT 8900D is, or even the QYT brand as a whole. I just got an 8900D and so far I'm liking it, but I haven't put it through to much testing yet. It is definitely an inexpensive unit, and it looks a lot like the Radioditty DB25G. I'm definitely not recommending it yet, as I haven't used it enough to do so, but it's doing pretty good thus far.
