### 4/5 — В целом не плохо

*2019-05-17*

Мануал нужен не только на английском, но и на русском. Согласен, что русский корявый но хоть как то облегчает понимание.
Нет Sinamics DCM (DC-Master) когда появится?

**Developer response:** Благодарю за отзыв! Русский перевод у Зименс не просто коряв, он страшен. Если бы они гуглом переводили и то лучше бы получилось. Вот, честно, я просто не хочу участвовать в распространении этого. Sinamics DCM уже занёс в список на заселение )

### 5/5 — Excellent App

*2018-11-02*

Must have

**Developer response:** 🙂👍🏻

### 4/5 — Error en la aplicación

*2018-09-10*

Está bien  solo que al momento de elegir el variador genera un error fatal

**Developer response:** Lo siento por tu mala experiencia. Mejoro continuamente la aplicación y corrijo los errores. ¡Gracias por la información!
