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.

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.

This Probe has a scope too!
I was totally shocked and surprised that this Probe had a little "Lab Scope". Using A/C Voltage screen, I got the 'Scope' and Frequency and Duty cycle. It was able to 'see' my ignition coil primary firing! I would not be making a lab scope diagnosis from here, but, this is great for that first 15 minute view into 'What is going on here'? I am looking forward to proving it can 'See' things like Purge valve duty cycle, along with blower motors, fans etc! The other Probe features appear to be very good and normal. Positive and negative tip, circuit breaker, logic probe indicator, continuity, tone, Ohms, etc. Remember,TRIGGER CONTROL! Don't put power or ground to any computer circuit. Those are the really small wires. If you do, you will surely burn up the computer,.... you know....'Let the smoke out'! It is safest to disconnect the particular load from the circuit before trying to power it up and see if it runs, ie: UNPLUG IT! Happy Trails ,
