No it isnt an arbor. I in fact have an element DBX. I have had it for five years and honestly I love it. Who cares if its chinese, 95% of everything is from there now anyway. It will work fine, particularly for a beginner. Ive done BC with it, groomed, east coast, west coast...and its held up great! Its relatively stiff and will hold up just fine
I will say the bindings are not good nor are the boots that would most likely come with the package. But the board itself I like and still use.
Keep it, learn on it, then buy up.
