I love this, it's convinient, it's easy to use and I can see myself using this a lot.
If you steam pumpins, carrots, they tend to leave stains behind but it's fine. I bought a sponge (similar like a bottle cleaner) and my mum fills in with hot water and leaves it aside, so when I'm back home, it's easier to clean.
As for the blades, I "fold" my sponge in to and slide the blade in between so I wouldn't cut myself.
No regrets buying this
