I don't know why this timer has received mixed reviews. My opinion is that it is sleek and stylish and goes very well with my other kitchen appliances. It is easy to set, just push how many minutes or hours you want, but if you want a lot of minutes then you just push and hold - wait for a beep and then it will quickly scroll through the numbers. If you want 45 minutes there is NO NEED to push minutes 45 times, just have a tiny bit of patience and it will quickly scroll through for you.
I have a 1 story house and I can hear the beep just fine, I think it is plenty loud. It beeps 60 times, 1 per second which I think is enough time to get across the house to check on your food.
I loved this timer so much that now 3 months later I bought another as a present. You will not be disappointed with this timer. I bought another one on amazon and it was truly Junk. I returned it and bought this one and am so happy.
