I have one of these, too, and I’ve never been able to use it. Would if I could, it’s brilliant! But in my last flat it was too tall to fit under the cupboards, and in my current one it’s too wide to fir between them.
I have a dishwasher, but I use a dish dryer as a ‘pre-washer rack’ because my ADHD ass can never empty a clean dishwasher quick enough to avoid dirty dishes piling up. So the dryer rack keeps dishes from blocking the sink. Stupid problems sometimes require stupid solutions.
Nah that’s just in the pictured configuration. The baskets and all the accessories just hook onto the rack frame so you can move things around to whatever config you want. Do the dish baskets on top of each other and leave the ‘flatter’ bits (like the knife block) for over the actual sink, much better config. Thirty second job even with the dishes on them.
