So here’s the rundown that led to my well-spent purchase of this adapter.Thanks to a collision with a deer, I had swapped the headlights on my 08 Grand Cherokee to the SRT8 style because I wanted projector low beams and not long after, I was still unimpressed with how halogen bulbs perform in projectors. I say STILL because I drove a 14 Sierra for some time and the halogens were so lackluster in the projectors I didn’t like driving it at night, despite how good the cutoff and spread on the projectors were.So I bought a set of Fahren LED bulbs. The performance and color was a stark improvement, but it left me with the downside that when the bulbs are turned off, they stay lit very dimly and flicker until the Jeeps accessory circuit is off for so many seconds.I then learned that OBD JScan was a thing and it could help my situation. It listed this as one of the recommended so I ordered it and then bought the $20.99 license on JScan waiting for it to ship.Upon receiving the adapter, I plugged it in with JScan open and paired to it almost immediately. I will say that it has worked without issue since I got it. I do find that even if the adapter sits idle (red LED lit) for a long time, it never drains the battery. But that is where the good of it ends, at least for solving my problem.According to videos and bits of info I came across, enabling the High Intensity Discharge option as well as the Quad Headlamps option will fix it. Now as my luck would go, my Jeep is an oddball.. the HID option was already enabled, despite it having the 9006/9005 wiring, not the D1S/9005 wiring. So I enabled the Quad Headlamps and then only my right low beam would come on and still flicker once turned off. So I disabled both options and then they were back to normal but the fans were no longer screaming like a mad demon escaping hades for the entire time they are on. So I left that as is and invested in those in-line resistor wiring harnesses and now both low and high beam LED bulbs shut off completely within maybe two- or three-tenths of a second of turning them off. Not instant but still faster than a halogen at full intensity can dim to off.So although this didn’t solve my problem, I did come across a resolution and this still has a ton of use for me. I don’t have to worry about getting a code scanner because I can see all stored and active codes on my phone through JScan. Plus there’s a lot of features on JScan that you don’t have access to through your personal settings in the EVIC. I enabled the “premium” TPMS display in the EVIC so I can see what PSI the sensors are reading. Interestingly enough, for the Illuminated approach, on top of the 3 available options, there’s also a 5 sec. option which I ended up settling on. I got to enable daytime running lights on the lighting circuit of my choice. The choices being: fog lamps, turn signals, low or high beams. I guess that’s one upside to the vehicles lighting relying on CANBUS. You don’t necessarily have a dedicated DRL circuit like a lot of GMs and most new vehicles, meaning you can go for the Tacoma look using the turn signals, or if you want to go with what seems to be the default option for the Chrysler umbrella of brands that came enabled with it in North America, use the high beams.Overall, it may not have worked for what I needed, but it paid for itself with all the things I was able to change and see. Plus being able to see live sensor data through JScan and also being able to high idle the engine when trying to jump someone else’s dead dead battery. And knowing that I don’t need anything expensive or have to go anywhere to be able to see and clear CEL codes makes life a lot easier. But with JScan, ahh endless possibilities.I see I got into a bit of a ramble, but it might come of use for future reference.To wrap it up, most likely if you’re needing an adapter like this, I would suggest going with this one. It’s well worth the cost, and from what I hear works with most all mobile apps and it looks to be the highest rated BLE4.0 adapters. I’ve had no issues and with Prime free shipping, I got it quick and on time.The ONLY con I have for this adapter is the LEDs. The red Power On LED is fine and the green Communication LED is fine, but the blue Bluetooth LED is what annoys me. At night, the continuous flashing on and off is so bright and distracting. If anything, it should flash while it’s pairing to the device/app then stay lit solid while it’s connected to the device/app. I hate trail driving at night using my phone dimmed down to keep an eye on all my temps etc. and yet I can see that blue flash light up a lot of the interior. Other than that, it’s a flawless product I can’t recommend enough.

Great product! I drive a 2015 Jeep with over 130k miles so I've definitely got my money's worth from it! Easy to use and so it's use friendly. Readings are accurate and the process speed to give you the code is quick. Great value for the money and recommend it to everyone I know that does the wrenching on their own stuff or just want know what you need to tell the mechanic is wrong.

Bought this so I could make some adjustements to a few items on my Jeep such as TPM system and tire size. Worked like a charm. Does so many things as well, still need time to figure out all it can do...but it is well worth the price.

1) I have a OnePlus 6T phone which is an Android based phone2) Attempted connection to OBD using phone Bluetooth a) Phone saw both Vlink IOS and Vlink Android devices for connection b) Tapped on Vlink Android and no blinking blue light on OBD, and no action on phone c) Tapped on Vlink IOS (blue light blinking) and phone connected right away3) Even though phone didn't indicate that it was connected yet, Vgate connected to OBD Auto Doctor app through the app.4) Downloaded “Car Scanner” app and it saw the connection and I was getting data from my car right away5) Second day, would not connect to my cell phone at all today. Attempted same as item 2 above.6) Tried to connect on my Windows 10 laptop. It only saw the Vlink Android, but it would not connect.THESE ARE COMMENTS FROM CONNECTING THE SECOND Vgate UNIT (I had another unit sent to me on plans to return the first unit)7) Attempted connection to OBD using phone Bluetooth d) Phone saw both Vlink IOS and Vlink Android devices for connection e) Tapped on Vlink Android and no blinking blue light on OBD, and no action on phone f) Tapped on Vlink IOS (blue light blinking) but phone wouldn’t connect this time g) Phone wouldn’t even connect through the Auto Doctor app8) Attempted connection to OBD using Windows laptop h) Laptop saw Vlink Android device and connected to this unit i) Used trial version of Auto Doctor program for Windows 10, and it connected with no problemsAlthough the Vgate unit didn't perform as expected, I found it workable enough where I can use it as a small portable OBD scanner with my Android phone while driving. I seemed to have the best results with the Car Scanner app (paid $4.99 for full featured app), even though Vgate was supposed to work well with the OBD Auto Doctor app. I gave up on getting it to work with my laptop.Vgate customer service was quick to respond to my concerns at all times. I just didn't get the expected results from the device. I would still highly recommend this device as it is a nice, portable Bluetooth OBD scanning device that can work well with a phone app. It was money well spent and worth the price!I had purchased an Innova OBD2 code scanner (only reads and resets) a few years ago, and I believe I paid around $200 for it at the time. Vgate for $32 and Android App for $5 and you can see the big cost difference already and ability to get more features for diagnostic work.This device and the Car Scanner app with it's features did help me to diagnose my car troubles and make the repairs for a lot cheaper than it would have been to take it to a repair shop.

Works great and perfect to use with JScan . 2008 Jeep Wrangler I can do whatever the dealer could through my phone

I purchased thos for the "Jscan" app for my 2019 Jeep JLUR. Connected easily. Works great every time I use it. I would recommend it for ease of use and quality.

This does exactly what I need it to do, and is great for BimmerCode on an iPhone. It is also smaller than I expected.

Works perfect on multiple vehicles

Hay que pagar la aplicación, pero te ahorra mucho

Très bonne qualité

Auch für EAuto geeignet.Konnte sämtliche Daten der Hochvoltbatterie auslesen.Temperatur, Zellspannungen, Kapazität. Einfach super. Habe noch so ein Billig Elm mit dem es nicht ging. Aber der hier ist super.

Product is genuine but received wifi variant not BLEShipping was not through amazon. And i had to return it on my own.Very bad experience from amazon’s end.
