As expected; lightweight.  Magnetic cord hold strong but does disconnects when pulled on.
It is a bit small for my large head, but fits my wife well whom is most likely to use this anyways.  It has a nice storage bag and arrives with all you'll need except for the USB power adapter.  If you are like me you already have extras of those.  It is certainly nice that it does not have a battery to add weight and that needs recharging before use, but having a cord attached is not ideal either.  The magnetic release works, though you will want to be sure the cord is routed so it does not drag items off your night stand before the tension is sufficient to detach it.  I won't hold that against it since I knew that when ordering it, just something to consider.  The cord and controls are sufficient while remaining light and compact.  I think the price is reasonable for a heated sleep mask of this quality.
