My only negative is the lack of ventilation and airflow on mine, but again that's based on the usual heat here. I have noticed in cooler temps there is more airflow under the chin and neck area, which I solved with a Buff as well.
The Northeast US is roughly halfway between Norway and Texas in Latitude, and I think the 551 is very near perfect as far as venting goes. Its warm on hot days (but so is every helmet) and its cold on freezing days (again, so is every helmet). I just came back from a trip where I took a ride up the Mt Washington Auto road, it was 87 (30.5c) at the base and 39 (3.8c) at the top. I simply closed the vents and visor as it got cooler and opened them back up when I was heading down.
