Be also aware that there are outright fakes around. This one did not have any silicon inside.

Certainly cheap…. BUT

On the ublox site there is a table indicating that the KT is a standard precision engine. On the same table, the UBX-M8030-KT-FT is required for timing:

So, they may be cheap, very cheap, but are they really what a TN would want?
