This handheld is great. It checks for emission readiness with one button push. You can also take measurements while you do your drive cycle for emissions. The code reading is easy and you can see data from other monitors built into the car. This is the most valuable car tool you can own.

I was looking for a budget friendly scanner that showed live data. This works well and I have used it countless times already. I didn't like the way it displays Fuel Trim values when specifically selected versus when showing all data. For the money, it's hard to beat this unit though.

This tool will pay for itself! I have used this tool to diagnose a "check engine" light on my Ford F150. The initial code showed a bad catalytic converter, but by using the more advanced features of this tool, I was able to eliminate the catalytic converter as the problem. Given that they cost anywhere from $400 to $1600, I'm really pleased to know I don't need one. This tool is very intuitive in the way it's set up. The buttons are clearly labeled make the whole process very easy.

Very good for the money and quality is good. Works excellent used to know my bus dt466e has both style plugs the newer style and the old style used it on both plugs works perfect

I received it when promised, it diagnosed my pick up's problem and saved me I am sure what would have been hundreds at an automotive shop. I highly recommend this product to the DIY, very easy to use and read results. This product exceeded my expectations.

I needed a scan tool that could read a variety of vehicles mostly diesel and this fits the bill. I was not expecting a lot of testing from this mostly just to show me what cylinder is missing to narrow down the problem and this works very well on everything I have tried so for. Example: it worked on 2004 International 4300 box truck, 2007 Isuzu 5.2 box truck, 2003 Freightliner 5.9 Cummins, 2014 Chevy 6.6 Duramax.
