yes I own one.
It syncs lower than the hg612, and if interleaving is enabled the FEC overheads appear to get applied twice, so when interleaved it syncs way lower than the hg612.
On the other hand its a device using the same chipset as the ECI modem, that has a GUI and on my line the error count is noticebly lower than the hg612.
As a router tho I think its maybe ok but not great, it doesnt have various advanced features, cannot be used as a bridge and the price point is/was also high for the spec. Plus I think it looks ugly
