### 3/5 — Doesn’t allow 950 watts

*2023-05-27*

The initial setup of the oven allowed entry of 950 watts but it changed to 900. I didn’t proceed any further, since my oven is 950 w. The Ui otherwise looks very nice.

**Developer response:** Thank you for your review. Considering operability, we set it in units of 100 watts. I'll look into it for the next version upgrade.

### 5/5 — 超過はないよー ☹

*2020-09-29*

うちの電子レンジは時間が長くても調理可能なので、数字で示してくれないと困ります･････････。

**Developer response:** レビューありがとうございます。改善点として検討させていただきます。
