Okay, this one was really an impulse buy and in no way a necessity. We have a very nice freestanding colander. We basically got this for two reasons both relating to our sink.
1) Our double bowl sink is pitifully shallow. If you are cooking anything of any complexity the dishes mount up on both sides of the sink fast and then you have to clear out a spot to put the colander (not to mention fill a pot, but that's another issue).
2) Because of the aforementioned shallow sinks the big colander
compounds the previous dish congestion problem once it has been used and now needs washed. Plus it is fairly difficult to wash with all it's little holes.
Enter this little device.
Unfortunately this does not work on skillet with short or rounded edges so if you were hoping to drain meat or some such this is not the answer. I tried it on my smallest and largest pots and it fit all of them except my small cast iron pot (which I use constantly so this is unfortunate). Again the edge on that one has a roll to it that is just a little too large.
However, it fits nicely on pots with straight sides at least the height of this clip (slightly under 2"). Even has a little cut out for the offset edge on lots of pots. Solid piece of wide spring steel plus this silicon gripping pad gives it a solid hold.
Some reviewers thought the holes were too small and it took too long to drain. Not sure if this is something that the manufacturer has changed since but I drained a medium sized pot of water in almost no more time than I would have if I were pouring it directly into the old strainer. It is dishwasher safe so cleaning should be a breeze and also supposed to be BPA free. I'll have to update once we see how useful/used this actually is...
Update 9/18: Have only used this once in the past week but discovered a few little hiccups when I did. If you have a recipe that calls for you to drain some pasta, then do something with a sauce in the same pot and then put the pasta back in this product is not ideal. Also there is no way to really shake all the water off of shells that hold water without the shells jumping out into the sink.
