What Experts Agree On
What Experts Love
- ✓ Scan-to-Cook reads a packaged-food barcode in the SmartHQ app and pushes the exact time and power to the microwave, so a frozen entree cooks to the box spec without punching in time and power by hand.
- ✓ It is the only pick here that speaks both Alexa and Google Assistant, so you can start it, add time, or change power by voice from any room regardless of which ecosystem you already run.
- ✓ At 900W in a 0.9 cu. ft. cabinet it slots onto a normal counter or apartment shelf without the bulk of the 1.4-to-1.6 cu. ft. bodies the other smart picks ship in.
- ✓ Wi-Fi setup runs straight through the SmartHQ app rather than a hub, so there is no extra bridge to buy to turn the scan and voice features on.
Common Criticisms
- ✗ It uses a standard magnetron, not an inverter, and Consumer Reports rated its heat evenness only fair on a reheated bowl of mashed potatoes, so large reheats can finish unevenly.
- ✗ Scan-to-Cook only helps with packaged foods that carry a recognized barcode; fresh leftovers fall back to the manual buttons.
- ✗ Owners and app reviewers repeatedly knock the SmartHQ app for buggy setup and dropped connections, which can sour the smart features that are the whole reason to buy this model.
