This level of quality at this price is really impressive. I spent a lot of money on Ali, and this product is definitely among the top 3. I highly recommend it.

A nice addition to your dashboard. Too bad you don't get a suction cup to attach it to the window. Furthermore, he does what he needs to do. In my car, the cover of the OBD scanner no longer fits because the OBD plug is sticking out. Shipping did take a long time, but I never find that that bad.

Tested on sandero iii, it works. At first i thought it takes forever to initialize, only to realize that i have to start the engine for it to work. However, it keeps working even after i take the key out. I set the auto-off time to 10s but it seems to ignore that setting so i just unplugged it to turn it off. Only tested obd2 mode.
