The same thing happened to me with the Rx the second time I used it. Only had it 2 days. The rubber gasket broke up in my food and was in very tiny pieces. Made a huge mess in my kitchen. All over the kitchen cabinet, floors, walls, etc. Couldn't get the blade off of the cup. Had to return the unit. I had read similar reviews before purchasing, but decided to try it anyway. HUGE disappointment because I really liked the way it worked. I returned it and got the Pro 900. However, after the second use of the Pro900, the unit started leaking. Help???
