Query: Useful for new sleep-deprived parents sharing duty

Some of the reviews here made us nervous about buying the product, but overall, we've found it extremely useful for coordinating care for our newborn. We have not experienced the quality issues after using it for 5 weeks. I also keep a paper log of the items this product tracks, but since my husband can remember to push a button, but not to write a diaper change or nap in the log, this makes it much easier to coordinate care. It's especially helpful late at night, when I'm waking up after just a few hours of sleep, to determine if I need to nurse him. It includes a back lite as well as a small flashlight, which is great when you need it but don't want to wake everyone up with the overhead lights. One feature that would make this better is a counter, to track how many times a timer has been reset in a 24 hour period.
