I have traveled through this checkpoint many times. I also went through other checkpoints on the border with Ukraine. Everywhere +- the same service. As for the "Mohro", it is easy to leave for Ukraine, and return as a fort. The queues are terrible on Saturday. The staff varies from polite and intelligent to boorish.
There are practically no queues, it takes from 1 hour to 2 hours to cross. There is a bank, open until 21:00. Insurance companies also work mostly only during daytime hours. There is also a duty free service on the PP.with a good selection of products.
There is no road. The point is small, more for passing transit. There are practically no passenger cars, trucks are flowing. I was driving in early November 2020.
