Brilliant and portable.
Purchased this OBD2 code reader to check mine and other vehicles to make sure their are no faults on them. Especially good if you are thinking of purchasing a new vehicle. Just plug it in and do a scan, it will give you any fault codes that are present and also for codes that have been previously stored in the ECU

Ottimo
Dopo un primo impatto non proprio positivo per la mancanza di manuale d'uso in italiano, mi sono armato di pazienza ed ho scoperto una volta impostata la lingua la facilità d'uso del prodotto in oggetto l'ho usato per la mia mercedes e si è comportato in modo eccezionale ha diagnosticato degli errori e li ha azzerati dalla centralina facendomi risparmiare tempo e denaro l'unica pecca mi sembra che non riconosca tutti i difetti quindi se non li trova non perdete tempo provare qualcosa di più professionale per qualità e prezzo consiglio

最高
高年式車も低年式車もチェックランプ消えました。英語の単語が少し分かれば何となく操作出来ますが、出来れば日本語にも対応して欲しい。

Dummy proof
Awesome scan tool that anyone can use to check and clear the dreaded check engine light. I've owned the more advanced much more expensive scan tools and this one def gives you more bang for your buck!!! It does everything one 3x's the cost does with complete ease. Large screen that is very easy to read, easy to follow directions, a complete library of codes, a search option, will provide graphs if desired, has a print featureand real time data you can track while driving! I couldn't be happier!!! I'm gonna be sending some out as gifts!!
