Haha - I watched that a few days ago when I was considering buying one!Correct the tray just lifts off. Its a storage unit. & worstation. The plastic containers that come with Occre kits fit directly in the draw slots.
My Ulisys ( 1m long ) is curently sitting in the cradle top of it. It is very stable. For its size and cost it is very good value. There is an unboxing on my youtube channel
