### 5/5 — Très bonne appli

*2013-03-25*

Je suis traducteur, je m'en sers souvent et je trouve que  la terminologie technique est assez exhaustive.

### 1/5 — Déçu

*2012-08-20*

Pour un dictionnaire "technique" je trouve ça un peu light...
Je suis technicien en bureau d'étude et je ne trouve aucun mot rechercher

### 2/5 — Aéronautique

*2011-12-08*

Technique industriel uniquement, pas aéronautique.

### 5/5 — Très bon

*2011-11-08*

Aussi bon que la version papier
