Well guess what Cooper. Have you seen a broken flight deck? Yeahhhhhh didn't think so.
How long have flight decks even been out? Not nearly enough time for them to break. Yes, quite a few Phoenix decks have been broken. Compared to the amount sold, it's minimal. Also, considering how Phoenix replaces ALL of them, they're extremely legit and confident in their product. Flights have been publicly released for less than a month, not many people are going to break them in a month. Plus, not as many are sold as compared to Phoenix decks because most riders are young and want light parts.
And by the way, there is NO such thing as unbreakable! EVERY part breaks. Some parts last longer than others. It also depends how hard someone rides, and how they treat their scooter. Parts break, get over it.
