No frills.
It worked just fine. It is a decent product for the price. It helped me track down an issue so it did what I needed it to do.

Great deal
Great customer service. I had one burn out, had a new one the next day. This machine has helped me save customers a lot of money. I can diagnose sensors and find shorts, test Fuses and wiring with precision. I was even able to simulate voltage for the temp sensor to verify cooling fans worked properly. Very nice setup. I also tried testing injectors. It does work but its a little more involved.

Better than the first P200, more option and includes a circuit tracer that the previews model don’t have

Worked exactly as I hoped and then some. Fixed a Diagnosis I was chasing for days!
Absolutely cannot recommend this tool enough. It works exactly as I hoped and has loads of features. Wasn’t too hard to figure out. Plenty of cable length so no fear of it being annoying to use.The ground cable is a little short so make sure you’ve got some testing probes and wires for adjustments.Was chasing a No fuel pump No start condition that was hiding for days. Eventually found the culprit hidden in the Fuel pump assembly that holds the fuel pump together and allows the chassis harness to plug into it. Had a hidden arc damage in the connector on the assembly. This tool ruled it out by simulating power to the pumps making sure they were good but also fully testing the assembly to see if it worked.Solved the mystery and saved me a major headache. Would highly recommend this as it made my life so much easier.Yes it did come with a case too!The P150 model Fuel Pump testing worked flawless and was able to monitor Voltage as well.
