I have attempted to use this product about 10 times with no luck. I cannot get a cup of coffee that isn't severely watered down. I've tried all different degrees of grind, different types of coffee, different amounts in the cup. I can't get it to work. I really am not technologically challenged and I feel like I should be capable of using this product the correct way. I can't get anything that tastes like coffee should out of it. I am very frustrated because I love my Keurig brewer but I hate throwing away so much plastic. I really wish that it worked.
