Panasonic NN-SD688S

Pros
  • Cooking sensor prevents overcooking
  • Inverter technology for even cooking
  • Stylish design
  • Intuitive controls
Cons
  • Noisy
  • Bulky
  • Display can be hard to read
  • Reliability complaints

The Panasonic NN-SD688S is a midsized countertop microwave that earns high marks from several professional reviewers. This 1.2-cubic-foot microwave has a high cooking power of 1,300 watts, and it includes inverter technology, which is designed to heat food more evenly. Other features include a cooking sensor to prevent overcooking and a 13.5-inch rotating turntable. Owners appreciate the Panasonic's stainless-steel exterior and easy-to-use controls. However, some reviewers say this microwave is bulky and noisy, and we also saw several complaints that the electronic display can only be read from certain angles. More disturbingly, we read many complaints about this microwave's reliability, including a couple of reports of dangerous overheating. A more reliable choice is the comparably sized Kenmore 6633 (*Est. $140) , which is also less expensive. If you need a higher capacity, the 2.2-cubic-foot GE Profile JES2251SJ (*Est. $275) also earns good reviews.

The Panasonic NN-SD688S has been subjected to detailed professional tests at ConsumerReports.org and the Good Housekeeping Research Institute. Wired also tests and reviews this microwave, rating it on a 10-point scale. The testing criteria are not very detailed, but the review provides good insight into how the Panasonic microwave performs in real-world situations. ApartmentTherapy.com, a home organization blog, also reviews the Panasonic NN-SD688S, and we found close to 150 user reviews at Amazon.com.
