My old kettle's lid keeps popping up so it needs replacing.
I bought one in sainsburys today - a russel Hobbs one. It's bloody useless, no indicator of how full it is (my fault for not checking), can't see a max indicator inside it so don't know if I'm overfilling, and for a rapid boil kettle it took 5 minutes to boil!!! 
It's going back as its poop!
What can you recommend? :)
