Bom dia, Toni. No worries, your English is 100 times better than my Portuguese.
I will agree with all who said fit is most important - there are few bad helmets anymore, only those that lack features you want or that don't fit.
Greater Boston motorsports in Arlington (outside Boston) carries both the Schuberth and Neotec. They'll knock 30 or 40 bucks off the price if you ask, but that's it. I tried both, found the Neo a much better fit, and will pick one up in the spring.
Everyone's entitled to my opinion
