I am a technician day to day and have been using it for about a month on my personal vehicles. Ford Maverick and BMW x5. The build quality and interface is beautiful. Very well built with a long lasting battery. What I loved the most was the interface at how everything was very easy to find especially with the Topology view. Something you only see at dealerships. This is a life saver to see the modules disconnected or communication on which line. Very similar to dealership software especially if you've used BMW software you'll know what I mean.I've used it on my Maverick and found out that my back up cam module was down but had a TSB from Ford notifying me of a recall. Saved me honestly on time and diagnostic. Next was my BMW x5 that I had used the TopDon One to help me change my transmission fluid, transfer case and battery. The instructions that prompts you are literally the same as BMW software allowing you to open and close the valves to drain fluid and reset adaptations which is a must. I also swapped out and coded my new battery which I was able to input the capacity and amperage. Overall, Ive been using it for about a month now and absolutely love the features of it being a bi directional tool with the option to program and code vehicles. Please keep it mind that on certain vehicles, you will need to purchase the token for a specific manufacturer but that is standard. Under Rights Inquiry you can see rights for OBFCM or NASTF. You can register your account and shop info with the capabilities to email you or the customer the whole vehicle report with pictures and data of your findings. It has a browser built in to do any searching on the web. A Lot of people may have mixed reviews of this scanner compared to others and that's their opinion as well as mine. The level of uses this has compared to Dealership is very close. I'm very impressed . Topdon customer support has been A1 with new releases. Since I've had it, I've probably updated it at least 15 times due to the scanner being so new. This is a good thing as it's constantly being updated. Any issues you can literally upload the logs to their support Team. The scanner is a powerful tool and not many realize the uses for active tests or bi directional especially with newer vehicles/ EV. The dongle and scanner can both be updated to the latest firmware and protocols but if you're not used to this level of OE capabilities, I'd try a different scanner from Topdon. Yes, it's that powerful. For the price, you're not going to find a scanner with this level of features for this price without going to the dealership or paying over $2k for those scanners and licenses. I can justify paying for a token on my own vehicle and it'll still be cheaper than taking it to the dealership. The AI assist is ok only because I don't really use AI to diagnose a car. Rather look at the data and freeze frames. I have yet to check the " Coding" feature with my vehicle as yet but once I test it and try it out I'll give a 2 month update. Review: great tool for pros - I've been using the Topdon One for a week now to test as many of its functions as possible. I work in a large shop, so there are many different car models and years. Firstly, when I received the Topdon One, I was impressed by the quality and the feeling of sturdiness when you hold it. It opens very quickly, and registering the device with Topdon is simple and fast. The advanced topology is superb in terms of usability. It doesn't just show CAN on pins 6 and 14, but also identifies other networks. A report is generated after scanning all the modules and is easy to print, or you can send it via Bluetooth, which is very convenient. The device is very fast, and the graphical mode is very useful. You can display up to 12 different parameters at the same time. You can also combine four graphs, which is perfect for checking ABS problems. There are also 50 maintenance schedules accessible via a very user-friendly menu. In addition, it also comes with a J2534, which provides access to manufacturer programming. I sincerely believe that for the price, there are no comparable options. It was a very good first impression. ## Features - Dual WiFi & 10.1" Touchscreen: Provides a stable, high-speed wireless link 3x faster than bluetooth, and a responsive, professional interface.

There’s direct links from the trouble codes to search their meaning and give you a variety of very helpful information. The unit is very well constructed with an excellent screen for watching training videos or whatever you want to look up. The graphics on the live data are out of this world!! I’m shocked by how low the price is for all the capabilities you get, this rivals tools twice the cost and it wins! The AI assistant features keeps getting more powerful with updates. It connects to vehicles quickly and the VCI allows for actual programming not just coding. I couldn’t be more happy with the purchase. I have a Snapon Zeus I haven’t used since I got this Topdon ONE and the Zeus was 10 grand. Don’t bother looking further this is the Best Buy out there for advanced capabilities period! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/807443764-one-bidirectional-scan-tool-10-1-obd2-scanner-with-j2534](https://www.desertcart.be/products/807443764-one-bidirectional-scan-tool-10-1-obd2-scanner-with-j2534) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-23*
