Reacting with the note you add in the "Disclaimer", the installation itself is a problem for an ordinary investor. In addition to the cost of the atm price + shipping fees, someone should be hired to install and maintain the machine.
ATM providers can't assist their machines all over the world. It's so risky to just start an investment with big money without having the right tools to maintain it for long run .
Very well noted excepts. Maintenance is key to sustaining this investment in the long run. However, it is a good investment to look into.
