I really love this sink!  
We don’t have a disposal so the hidden drain basket is my absolute favorite feature- so much nicer than the alternatives.  
We love the colander but I actually put my silicone colander in it and it keeps it off of the gross sink bottom.  Or I have my kids put their drink glasses in it before they pour their drinks and any little spills all go directly into the sink.   
I use the drying rack a few times/ week but it folds down really small so its super convenient to leave it out all of the time.  
The whole sink looks great and has a great price point - I would definitely buy it again.
