Query: Big Flaw

This kettle does its job really well but it has one big problem with it - there is no way to open the container to clean the bottom of the pan. In about 2 months of use, my kettle got scaly lime deposits and it was disgusting to use the water in the kettle after that. I tried cleaning it with CLR but nothing came out and I had to throw away the kettle. If you are in the mood for a disposable kettle you can go for it but otherwise stay away.
