Love the expandable colander by kitchen Aid!

Fits on my Karron sink well, but would fit on. Any sink due to the adjustable arms. Easy to use!

Good concept and very sturdily made with adjustable width that can accommodate the depth of various work station sinks. The downsides are two: One, it's heavy at almost 2 pound (my old round wire colander weighs less than 9 ounces). The adjustable bars cannot be locked in place and tend to shift, which may cause the unit to fall off the work station or sink edge support into the sink. If you want to hang the colander from one of the adjustable bars rather than store it in a drawer, the bar is likely to expand to its full length, which doesn't work for me.

So sturdy and convenient. Just wished it collapsed because it is on the larger side to store
