Digital Timer with Memory (remembers last setting used) and an upgraded 'EXTRA POWERFUL' magnetic fastener for hanging all types of artwork, pictures, calendars or notes on your fridge. Designed with special upgraded heavy duty extra strong magnet. Start/Stop button is the On/Off switch. When not in use, no battery drain. Obviously its a digital timer, but it's also great for hanging the little ones masterpieces on any metal surface. Displaying that new Picasso has never been easier, or more elegant. When buttons are pushed while stuck on fridge or eventually slide down from door openings/closings like most of the cheaper models, won't wobble. Takes 2 hands to pull it off fridge. (Ok, just kidding, but it's a very strong magnet). Our initial product research of digital timers determined that most digital timers on the market that offered magnetic attachment have very low strength ratios as well as rear pivot points. Beware of timers that don't have flat magnet backs. They wobble when timer buttons are pushed causing timer to pop off fridge. We made it a priority to manufacture ours using a flat back surface (no pivot points) and upgraded magnet designed with a much higher field strength intensity. It won't pop off fridge with the wobble factor when front buttons are pushed. It sticks and stays stuck. Plus it looks great just hanging around. Did we mention it's also a great timer?
