### 5/5 — Top App mit Verbesserungspotential

*2022-12-27*

Super App, gute Visualisierung!

Einpresstiefe im Vergleich wäre noch super.

Noch wichtiger fände ich zudem wenn die Abweichung vom Abrollumfang gleich ausgerechnet würde & mit den TÜV-Anforderungen verglichen/bewertet wird.

### 4/5 — Gut

*2019-03-07*

Ich bin bis auf zwei drei Kleinigkeiten ganz zufrieden. Wie schon angemerkt, wäre die Einpresstiefe noch super. 
Was mir auch fehlt und wichtiger (für mich) ist, wäre die Angaben der Abweichung von Abrollumfang und Geschwindigkeit Prozent (%). Ich muss das immer extra errechnen.

### 5/5 — Super App!

*2019-02-10*

Wenn Sie noch die Einpresstiefe / Offset in den Vergleich einbinden könnten, wäre die App perfekt! Absolut das Geld wert!
