have the Creader V for about a year in private use and these can thoroughly recommend. The device reads OBD2 data from the engine control unit, also supports a variety of protocols. Live data (coolant temperature, Drosseklappe, air mass meter ...) are just as Freeze Frame data support (operating state when an error occurs). The appliance and sluggish responds to something, but it does the job. The chart feature has no user-programmable time window (something by 30 seconds fix), but again, the purpose is achieved - reading the maximum mass air flow sensor signal when passing acceleration (to a common call "on suspicion exchange part") for example, might range from completely.
Those who do not claim to data logging and zoomable charts will be very happy with this unit. Price / performance are quite 5 stars, the power alone considered 3 of 5. Adequate, but not abundant. Those who want more, the need to pay considerably. Anyone who spends only 30-40 for common hardware store goods on the other hand gets significantly less functional. Reading and deleting more than one error code can not these cheap devices, live and freeze frame data in which not there.
A small warning yet: These cheap readers can all read and delete only fault the engine control unit. ABS / airbag or other errors comfort systems such as radio / climate are in the price range of Creaders explicitly not included.
