Simona Halep bears a perfect record in 2015, and her form could be down to her new equipment.
It has been a case of new racquet, same Simona Halep so far in 2015.
The Australian Open third seed is unbeaten this season, and moved into the fourth round at Melbourne Park on Friday with a 6-4 7-5 victory over Bethanie Mattek-Sands.
Halep has won 16 straight sets since losing the very first of her campaign in Shenzhen earlier in January, before going on to win the title.
Still with Wilson but brandishing a different model, Halep, 23, said she was pleased with her output using her new frame.
"It has more control, you know, also power I have with it. I like a lot," Halep said.
"If you feel good and if you like it, you want to play with it. I have more control and more power with it.
"I think now it's the best racquet for me."
Halep, who parted with Belgian coach Wim Fissette at the end of the 2014 season, had previously said she wanted to hire a Romanian coach in order to feel at home on tour - and to have a like-minded tactician working with her.
So it is not surprising where she likes to prepare for the Australian summer, despite the temperature in her homeland delving into negative degrees Celsius during the European winter.
"I like to train [at] home, so every time I'm going home to practice everything," she said.
Halep, however, could do with a Belgian mindset for her next clash, when she takes on Yanina Wickmayer in the fourth round.
As with her racquet choice, Halep is standing by her change and will not consult Fissette regarding the contest.
"No," was Halep's short reply, when asked if she would reach out to her former coach.
