"This is one of the most useful tools I’ve bought in recent memory. I regret not having picked one up sooner. It’s paid for itself after a single use. I had a shaking in a vehicle and I could not figure out what it was. I’m a home mechanic and was dreading taking it to the shop. This told me that thi..."

"Simple and easy to use. Even came with directions! I originally purchased the Ancel brand for $35.99 thinking it must be better but that one read my code fine but didn’t erase it and kept giving me a failed to erase error … so I returned it and took a chance on this cheaper one since so many peopl..."

"Been using mine for 3 years and it has been great. I leave it always plugged into my truck so that it is ready to use if I get a check engine light or even if I'm just curious about how the engine is running.It is well worth having, as it has saved more than its cost in not having to pay for diag ti..."

"I own vehicles from a wide range of years and needed a scanner to cover late 90’s OBD II systems. I reached out to Xtool to see if the D5S scanner would perform a Crankshaft Sensor Relearn on my ‘98 Chevy truck, and they were able to confirm it would after being provided with the VIN.I set up the sc..."

"Great little tool. Loads of codes. Great functionality. Awesome.price. perfect for quick code reading to help with the diagnosis of errors."

"Good for breaking into learning about more complex features of code readers. Has graphs you can choose to view instead of looking at numbers. It's like a wannabe oscilloscope but more like a graph. So it can graph your battery volts, fuel trims, O2 sensors, can read your RPM's, catalytic conve..."

"Fast, and accurate. Much more than I expected for the price. This diagnoses the refuel vapor vent lock up I had on my Ford Maverick when the more expensive tools at O’Reilly, Autozone, and Walmart didn’t, including the loaner OBD2 tools they had available that cost over $100.The app was also very ..."

"As a "shade tree" mechanic fixing my own vehicles I can't do much without a good (cheap) code reader. My old BT model would not connect to my phone, so I ordered this all-in-one setup. Works great, easy to use, no phone app or finicky BT required. Most surprisingly it comes with a decent little m..."

"Needed a cheap OBD scanner that I could keep in the car while I monitored when the car finished all the EVAP system checks so I could go get my state inspection. Autel is a known good aftermarket brand. Easy to use and read. This is not a bi-directional scan tool so its not supposed to be able to do..."
