And the saw dust from MDF will choke you quick though.I hate working with it anymore.It will get on anything and everything.I try to use nothing but plywood anymore.I've had my fill of MDF.It is no good in high Humidity or wet/damp or outside locations, if it ever gets wet once it is toast.That's were the durability issues arise IMO.
