"I thought I was pretty good about drinking water, but I would always end up refilling the same cup over and over and get annoyed with the constant trips to the fridge. The HydroJug ($20) is a half gallon, so I don't spend forever filling it up, and it's easy to carry around. But I go through at least three jug-fulls of water throughout the day, and it's so handy to keep by my computer. I have been recommending one to everyone I know!" — CS
