George North has praised Wales's clinical performance in this afternoon's 40-6 demolition of Argentina.
The Northampton winger was one of four try scorers as Warren Gatland's men offered the perfect response to last week's 24-15 defeat to South Africa.
"It was great, obviously," the 21-year-old told BBC Sport. "Last week we had a lot of errors, we tightened up our game to be more accurate and we showed that today.
"We didn't start the best last week but it's a massive competition for us, this autumn series, and it's good to get the win today.
"It was just a good performance all round, myself included. We played to our strengths and a were a lot more accurate."
Tonga are the next team to visit the Millennium Stadium in Cardiff on Friday.
