Portable, easy to use device with helpful app- definitely worth having!
OBD2 Scanner Review – A Game Changer for Understanding My Car! I recently purchased the OBD2 Scanner, and I have to say, it's been a game changer for me in terms of understanding my car and taking better care of it. Right off the bat, the first thing that impressed me was how portable and compact this little device is. It easily fits into my glove compartment or even my pocket, so I can carry it with me without any hassle. This makes it perfect for on-the-go diagnostics, whether you're traveling or just running errands around town. Portability and Design: The compact size of this OBD2 scanner is one of its standout features. It’s lightweight and doesn’t require any complicated wiring. You simply plug it into your car’s OBD2 port, and it’s ready to go. I’ve used it several times now, and it’s always quick and easy to connect. The plug-and-play nature of this scanner is really convenient, and since it's wireless, you don’t have to deal with a tangled mess of cords. It's truly one of the most portable diagnostic tools I've ever come across. Ease of Use – The App: What really takes this scanner to the next level is the accompanying app. The setup process was incredibly straightforward. I downloaded the app, connected my phone to the scanner via Bluetooth, and within minutes I was ready to start diagnosing my car. The app interface is user-friendly, even for someone like me who isn’t particularly tech-savvy. The instructions are clear, and the various features are well-organized, making it easy to navigate. Through the app, I was able to get real-time data about my car’s performance, from engine RPMs to temperature levels. The best part? The app provides diagnostic codes and an explanation for each one, which I found incredibly helpful. No more cryptic codes that leave you scratching your head! Instead, I was able to get clear descriptions of any issues my car might be having. The app also offers troubleshooting suggestions, which really helped me understand my car’s maintenance needs better. Helpful Information about My Car: I’ve learned a lot about my car using this device. I used to feel a bit clueless when it came to understanding what was going on under the hood, but now I feel much more confident. One instance that stands out is when my check engine light came on. I plugged in the OBD2 scanner, and it quickly gave me a diagnostic code along with an explanation. Armed with that information, I knew exactly what the problem was before I even took the car to the mechanic. The mechanic confirmed the issue, and because I was already informed, the whole process was smoother and more efficient. This scanner has also helped me keep track of my car's health over time. I now monitor different aspects of my car’s performance, which has allowed me to be more proactive about maintenance. Whether it’s tire pressure, battery voltage, or fuel efficiency, the OBD2 scanner gives me valuable insights that help me take better care of my vehicle. Relay Codes to Mechanic: One of the best features of this device is that it provides diagnostic codes that are easy to relay to a mechanic. In fact, I recently had an issue where the scanner flagged a problem with the oxygen sensor. I shared the exact diagnostic code with my mechanic, and he was impressed by how precise the information was. It saved time and ensured that the mechanic knew exactly what to check for, avoiding unnecessary guesswork. Overall Verdict: The OBD2 Scanner has been an invaluable tool for me. It's portable, easy to use, and packed with useful features that have helped me better understand my car and take control of its maintenance. The app is intuitive and makes it simple to diagnose issues, even if you're not a car expert. Plus, the ability to relay specific codes to my mechanic has made servicing my vehicle much more efficient. If you’re someone who wants to stay on top of your car’s performance, avoid unnecessary repairs, or just understand more about how your car works, I highly recommend giving this OBD2 Scanner a try. It’s worth every penny!

Powerful Inexpensive Tool
This Carpal device has a lot of features that others do not. I own several of these OBD devices and this one works well. It has several features that are handy. It can scan all systems for codes. It allows the user to select a vehicle which is nice because then it can provide the correct code descriptions. It has a built in battery test that monitors battery voltage through the DLC. This is a neat quick little test, however it is not a replacement for a professional battery starting charging test. The tool also has some performance meters to track vehicle acceleration and 0-60 times etc. Setup was quick and easy. Download the program, connect the tool through Bluetooth and then finish account setup and it is ready to go. This is not a replacement for a professional level scan tool but it is a handy little device that will pull all codes from all systems, clear all codes, scan engine data and provide OBD emission test results. Easy to setup, easy to navigate and nice clean data screens make it a good tool. It’s a lot of tool for a little money.

Get one for yourself, your family, your friends, etc.
I have a history with cars giving out on me at just the WORST possible moments. I wish I had one of these to see the problems from a mile off without having to be told by a mechanic later on. I can use this with ease, connecting to the app. I know ko one wants YET ANOTHER app on their phone, but this is an obvious exception! Not only can I et detailed info on my car, I get suggested repair options, too, in detailed steps. For anyone that is mechanically illiterate like me, this gives me that little bit of confidence to go into a shop and get the right tools the first time or be able to keep up with any mechanic that is explaining how to fix any future problems. i can also stay ahead of the curve in terms of when to check fluid levels, engine issues or be more alert of those certain car noises that come up that never happen once you get to to auto shop. A real treat to have, incredibly lightweight, but intuitive to use!

App Privacy Concerns
I wanted to like this tool as it indicated it would put my 2020 Kia vehicle into parking brake service mode so I could replace the rear pads - I never anticipated it would be such a security and privacy nightmare. The App requires you to agree to a terms and conditions that states that they use a 3rd party SDK and you have to consent to that usage - no where does it actually indicate what the 3rd party SDK is. The app indicates that the user (you!) is responsible for any action taken by your account, even if access to the account was unauthorized (hacked), even though they should be tasked with securing your account on THEIR servers. To that point, your account doesn't actually have a password nor is there a way to set a password, they send a numerical code to your email on occasion that you have to type in, so even if you want to secure your account with a long alphanumerical password, you can't. Who knows how secure their system is. The app indicates that you can cancel your account and request that your data will be deleted, but even if you do that they will retain your data to the "minimum periods specified" by law, but don't actually disclose what that is. Also, once they decide to finally delete your data, they only make a "reasonable" effort to do so. There are several other interesting lines in the terms of service around the app that I'd highly recommend reading if you choose to install it. On Android 9, the app continually runs in the background (and sends data..) even if you close it. You have to force quit the app in settings for it to actually stop running. There is a 3 vehicle limit which isn't disclosed in the product listing. I did test the functionality and it would put my 2020 Kia parking brake service mode, but the terms and service and privacy concerns mean it's going back. Buyer beware.

Just as good as more expensive options.
This is my second Bluetooth OBDII dongle after returning a much more expensive one ($160) and the TOPDON CarPal has almost all of the same features. The only thing left to be desired is faster load times in the app, but otherwise this is a great product.
