Overview
The Panasonic NN-SU66LS is a countertop microwave built on Panasonic's 1100 watt platform, sized to fit smaller kitchens without dropping down to a lower wattage unit. It includes a turntable and standard touchpad controls.
Longevity is where owner experience diverges: several reports of units dying between two and three and a half years sit alongside others still running well after multiple years.
- 1100 watt heating in a compact countertop shell
- Turntable rotates food through the cycle
- No interior light, unlike some earlier Panasonic models
- Dark gray cavity finish
Who it's for
Suited to buyers replacing a failed countertop microwave who want strong 1100 watt heating in a compact frame, particularly where counter or cabinet space is tight. Not a fit for anyone who specifically wants a lit interior to check on food while it cooks.
Pros and cons
- Full 1100 watt power in a smaller footprint
- Straightforward touchpad operation
- Turntable for even heating
- No interior light
- Dark gray interior makes food hard to see
- Some units reported failing within a few years
- Rust along interior seams reported by at least one owner
Performance notes
At 1100 watts on Panasonic's standard platform, it heats and reheats food at the pace typical of that wattage class, with a turntable that keeps food rotating through the cycle. Owners describe day to day use as straightforward, though several note the keypad is dim and the unit runs a bit loud in operation.
