Like all of the other OTC tools I have purchased this one did not let me down. The pieces are quality and i love that they come in a case to keep them all together. I have not had any issues with them in my couple uses so far.

Was able to get my o2 sensor out even though it was in a really hard place to get to.

These tools are OTC, a leader in tool design and manufacture. They do exactly what they are supposed to do, and they do it very well.

My set from matco was always really loose on sensors, especially the 02 one. For some reason this one fits a lot more snug and works a lot better. This is a good set.

Perfectly machined, even by my eye. Someone took the time to de-burr edges. Something you just do not see very often anymore. It's always some part that I get cut on and that burns me because I ALWAYS had to file everything I machined so customers do not get cut. What happened to quality? Well, look no further, you're going to find it with OTC.Now I have all the sensor sockets needed for near any engine. Zoom zoom..

Not the quality I expect from OTC. Made in China. But what isn't. The finish is very crude. May return it and spend more money on the tool truck.

I bought this set specifically to replace the front oxygen sensor on my 2007 Toyota Prius. This Prius sensor has a metal heat shield around it that requires a socket that is slim enough to slide inside the heat shield. The socket must also be long enough to reach to the bottom of the heat shield to engage the hex nut at the bottom of the shield, and it must also be short enough to be able to fit within the small area in the engine compartment where the oxygen sensor is located, on the down exhaust pipe between the engine and firewall, in order to have working room to remove the oxygen sensor.This set will NOT work for the first or front shielded sensor on my 2007 Toyota Prius, and probably will not work for other similar sensors with this same heat shield, because the overall diameter of each socket is too large to fit inside the heat shield. One of the sockets in this set can be forced to slide into the heat shield, but it is too tall to fit into the cramped area where this sensor is mounted, and you probably can't get it off once you install the sensor. I needed to tap it with a hammer for a while to slide the sensor off, it's that tight. It barely fits inside the heat shield.I had driven to every auto parts store that I could think of, with the shielded sensor in hand, trying to find something to work, without any luck, and after reading other reviews online that specifically said that this set would work for Toyota Prius, I bought it. It does not work for the front (or first, before the catalytic converter) oxygen sensor for Toyota Prius.The back, or second, oxygen sensor, after the catalytic converter, is just a standard sensor, without the heat shield, so just about anything will work for that, including just an adjustable or open-end wrench.I went to my local Toyota dealer (Toyota does not sell any tools, just parts) and asked their techs if I could see what they use. They use a Blue-Point, YA6675B, slotted, slim socket, that fits easily inside the heat shield, engages the hex-nut at the bottom, and should not have any issues fitting in the small, cramped space you have to slide this over the sensor on the exhaust pipe. I have ordered this part from a Snap-On dealer ($47, includes shipping) and should receive it in a few days. For those of you who don't know, Blue-Point tools are sold by Snap-on. Good luck finding a Snap-On dealer if you aren't a garage. I called the local NAPA store and the guy there knew a Snap-On dealer and had that dealer contact me, and I ordered it over the phone with a credit card. Four days to ship from their Chicago warehouse since it is so rarely ordered that it is not stocked in Snap-on's local warehouses.Update: I received the Blue-point. It was the perfect size, and fit into the heat shield, and worked perfectly. It was not a tight fit to get it onto the nut inside the base of the heat shield, something important in tight spaces. Seems Blue point made the right tool for this job.
