I purchased this kit after two of the four sensors failed in my 2009 Prius. I needed new tires for the front and thought I'd take the opportunity to replace all the sensors. The sensors I received are very similar to the OEM sensors that came with the car. I went to my local Walmart and asked them to install the sensors. I programmed the sensors myself as I have Techstream for Toyota vehicles. Programming was effortless, and when I hit the relearn button, the tire warning light went out. I'm very happy with how it turned out.
