This is a very easy-to-use timer, the big numbers are great and I can hear it go off quite a distance away! I use it a lot when I'm using my PC because time just seems to disappear when I'm back in the office working on it! The magnetic back is nice so that I can put it on my fridge.

Ex Output:
positive


Ex Input:
Never received item !!! Add-on item missing from delivered package and not discovered after allotted notification time had expired so no recourse as far as a refund. Shop with Amazon almost exclusively and dissappointed to say the least.

Ex Output:
negative


Ex Input:
I really loved this story. I didn't even realize until I was finished that it was loosely based on real events and real people. This was a true love story during a time that saw too many obstacles. I loved the characters and the sense of place. Well done!

Ex Output:

positive
