This new gadget can “smell” your meat and let you know if the stuff that is beginning to turn that strange shade of grey is still edible. Using a microprocessor and complex algorithms, the Sensor Fresh can take more than 2,000 readings in less than a minute, and comes with an extra sensor card that is good for 200 uses. Running on 2 AA batteries (not included,) the Sensor Fresh carries an MSRP of $89.99, with additional replacement cards available in two-packs for $9.99. We have an even better device that is a lot less expensive. If our princess of a cat won’t eat it, we know it’s time to let the meat go.
