Machine T3 ultra, it came used and discharging in 10lin, I asked to change the machine, I wasn't at home, only my brother, so they changed the battery and not the machine, then it started with the same problem (2 days later), I asked for machine change, only this time I was at home, the motoboy wanted to change the dnv battery, I said that only the machine, they changed it, guess what? Another used one with the same problem, I filed a lawsuit with Procon to return the full amount of my money.
