This device will drain your battery... as it did mine... if you leave it plugged in when not operating your vehicle.This makes the device only really useful in diagnosing issues.... after you've noticed an issue with your vehicle.Poorly designed. Cannot recommend. Mine is sitting in the glovebox collecting dust.

installed this into a bmw.unit works perfectly and i really liked it.tried to start the car next morning,flat battery,this unit drained the battery overnight down to 6v.Why dont these manufacturers think about their devices.

very handful for quick diagnostics

This is the best OBD I’ve used! It operates as advertised. I stumbled trying to connect it to the app, because I assumed I had to connect it with Bluetooth to the phone first. After actually reading the very simple instructions I discovered that it connects through the app directly. The interface is fantastic. The detail from a check engine light is extensive. I can’t wait to try to out their other products.

Package looked opened upon receipt. Sure enough, when I attempted to install the item the app indicated it was already assigned to another vehicle and would have to be released by the previous user before I could use it. Completely unnecessary headache for what was supposed to be a NEW item. Will be returning and likely acoid this company in the future due to poor product control.
