At 500 hours, a malfunction that cost 180 euros... problem with the SD card or the slot that communicates with the board... initially the problem seems to be the external SD and by replacing the card you feel like it's fixed... it works temporarily, then it freezes again and after all the trouble, you throw away 180 euros for a board replacement and feel like an idiot.

In about half of its life (1050 Z), it 'got stuck'. They changed the SD card. I paid 20 euros. It worked for 4 days and then the same thing happened again. They came again and changed the SD card for free this time, of course. It worked for 7 days and then the same thing happened again. Now I just can't get them to answer the phone, of course. Note: For every day it doesn't work, I lose all the customers who wanted to pay with a card. It's a big loss. Stay away
