If it had fewer stars, I would give it. I have had it for 2 months and it needs calibration, which can only be done at the company with a charge. Thankfully, because I have it for such a short time, they told me to bring it and we will see... The upgrade is also only done by the dealership, which is the only one that has the technology to upgrade firmware with a USB cable and also charges for it! Finally, in order for the service to check it, you have to fill out a form!!! I don't know if you need a protocol or if you have to stick a stamp...

The machine without any particular use occasionally produces counterfeit banknotes, even if you clean it. If by chance new banknotes come out, even if you have just bought it, you will need to send it by courier at your own expense and pay for the upgrade. Unacceptable behavior from the employee when I called and asked to do it myself with my own responsibility because I considered that the money for an upgrade is more than half the price you pay for it. Also, I am in a tourist area and I will lose a lot of time in this whole process because they do not provide instructions on how to do it yourself to avoid wasting so much time. It is better to get something cheaper that does not have reading problems all the time. The battery I bought for operation without electricity is also a waste of money for over a year and it was never useful to me. Generally, a bad impression from both the machine and the company.
