If you live on Avenida Monumental, República de Colombia, or nearby areas and wish to conduct your transactions at Banreservas, you can go to Patio Colombiano. Their staff is generally friendly and provides good service, and they also have a drive-through banking service. The only downside is the unreliable ATM (it often doesn't work).

Removal from the vehicle is difficult, it gets damaged frequently and takes a long time to repair.

You definitely need to allow plenty of time as they are not the fastest.
