content: Very good quality spinner. Large capacity (not easy to store if you have a small kitchen) makes it easy to wash and dry two large heads of Boston lettuce. Also used to wash herbs, vegetables and fruit. The spinner lid (with the knob) is pushed down and the interior basket spins. There is a brake button to stop the spinning if you're in a hurry. There is a little lock so that you can keep the knob in the "down" position for easier storage. Also comes with a flat lid so it can be used to store other things, both refrigerated and not. The base of the bowl has a rubberized rim so that the unit won't dance all over your countertop when you spin the contents. Solid construction and well engineered.
