Query: Flimsy, knob now broken

My machine worked well for a few months. I used it twice a week or so, making usually one cup at a time (the second cup comes out too watery to drink). Then the knob just stopped being able to turn. I've tried everything short of taking the machine apart to try to make it work again.To be honest I'm quite happy to have an excuse to finally get rid of this thing and purchase something better. I will never buy this brand again.
