What is Reddit's opinion of Lefebure NTRIP Client?

From 3.5 billion Reddit comments

There's a hint right in your application comments: "Foarte buna Pentru utilizatorii de rompos " -- "Very good [application], for ROMPOS users"

>Romanian Position Determination System - ROMPOS® is a project of the National Agency for Cadastre and Land Registration that ensures precise positioning and coordinate reference system ETRS89 European based National Network of GNSS Permanent Stations.

>ROMPOS® is based on Global Navigation Satellite Systems (GNSS - Global Navigation Satellite Systems) including GPS, GLONASS and GALILEO (in the future), providing complementary data for improving the accuracy of determining the position to order a few millimeters.
