The unit works (for anyone with fiat it WILL NOT work with MultiECUScan the ch340T usb chip just won't work) for general obd purpose it's fine or others vehicles. For multiscan get another chip like the ftdi chips
The soldering was also not the best. But all connections ware made so I guess it does the job
Device does not work with Renault Megane 2. ScanMaster app is useless for my car. When device used with PyRen, no ECUs could be found, still connected fine. Be aware, that device is built on chipset that has support under Win7 maximum.
