Exactly what I expected. If you have never used this type of tool, you need to try it. You will not want to use anything else again.

Did the job on an ADT door that had its original sensor removed.

Wow, I tried before without the tool and could not do it at all. However, ordered the tool and it was a piece of cake to change all the sensors.

the product does what it is supposed to, it is a low cost alternative diagnostic tool for techs that need to reference O2 cycling for catalytic converter performance or O2 troubles. The tester is good for driving the vehicle for emissions testing, so that the tech would know when the vehicle is ready for state emissions testing.

The Bosch oxygen sensor has a slightly different shape and length at the "probe/sensor" end, but threads in fine and has matching connector assembly as compared to the original OEM Denso sensor on my 2001 Lexus LX470. I bought it with the recommended slotted socket. Removal and replacement went smoothly and the Bosch sensor is working perfectly.

Excellent if you have a hard to reach O2 Sensor

It reads out the trouble codes easily and allows you to clear them (and turn off the check engine light) if desired. Easy to use and does what it is advertised to do.

Must have. Apply to threads of spark plug for easy removal next time around. Screw spark plug in to the torque suggested by manufacturer and apply permatex dielectri tune-up grease to spark plug boot (both ends of spark plug wires). Don't forget to replace oxygen sensors!

They do a good job or cleaning up threads. I bought this set specifically for changing a O2 sensor in my truck. The nuts on the sensor were probably 15 years old and very corroded. This cleaned them up enough to remove the old nuts and the new nuts went on easy enough. Good kit to have in your tool box.

Worked better than expected for replacing stubborn oxygen sensors.  I use this tool and a daily basis and never had any issues.

Very useful tool for cleaning bits of debris from a DSLR sensor.  Does not take the place of a wet cleaning but you can use it in the field.

I've been cleaning my camera sensor for years, using blowers, sticky pads, pec-pads, static brush and all the other assorted tools.  Usually it's blower, check sensor, brush, check sensor, sticky-pad, check sensor, pec-pad, check sensor, pec-pad, check sensor. Repeat.  Checking the sensor involved a penlight in one hand and squinting at the sensor.

The loupe makes the "checking" part a lot easier. I still try the "blower" part first, but then move on to the sensor pen.

The batteries were tough to install. It uses several "button" batteries, so battery replacement will be expensive. BUT it did include two sets.  Probably enough for a year or more.

It's a great addition to my cleaning arsenal.

The sensor cleaning kit was just what I needed to clean my digital camera sensor.

Not sure if this is safe for oxygen sensors. Had issues after using it, but I couldn't say if was the liqui moly anti friction treatment.

i love this thing for what it does for me:  it resets the computer, so i can pass my car inspection.  it gives me a code, but replacing the oxygen sensor didn't help the code go away.  i probably have a loose wire somewhere, but as long as my car passes the emissions, i don't care enough to look into it.

This device saved me when my CA smog check came up. Have a Nissan Rogue that is driven almost exclusively on streets. Wouldn't pass smog when first checked as some of the sensors had incomplete data. A mechanic offered to charge me a bunch of money to diagnose what was wrong, but a web search revealed that I could resolve the issue myself.  The web pointed me to this type of tool along with a reset procedure to get the vehicle sensors calibrated.

 I first used this device along with Torque software on my phone to verify the smog center's reading, and then to check the vehicles emission monitors as I drove ~200+ highway miles to complete the sampling data. I was able to monitor the car's emission computer real-time readings and see the point where all of the sensors had the data needed to pass the smog test. Cost of this device with software was about $30. The mechanic was going to cost ~6 times that.

Device and software worked well, no issues. Reader was easy to attach and connect to my phone via bluetooth.

Now that I've used this device once, I feel that it is an essential tool if you have an older car and mandated smog checks. If you have any doubt about your vehicle passing I recommend using this device or one like it _before_ you spend money on a smog check. Would buy again.

Wrench works as it should, it has the opening to slip over the leads to the sensor. was able to remove and install sensor without problems.
