Query: frustrated

I was impressed with the flavor this coffee maker produces, but very frustrated with the carafe not keeping the coffee hot. It is also IMPOSSIBLE to loosen the lid after brewing to pour a cup!!!! I had read other reviews, but thought it was surely not so bad. WRONG! I really wish I had paid attention more to the comments about the lid. Very frustrating. Wish I had paid more for a coffee maker that brewed to the right temperature:(
