No comment on the quality as I am returning it. I was expecting genuine Subaru parts, which I used to buy for about $40 each. This supplier only had three, so I reached out to them, thinking I'd bite the bullet for the extra $10. Imagine my surprise when I opened the package and found Sixteen TPMS sensors. These are not the Subaru parts I wanted, they are generic parts. They probably work, but I have no intention of finding out. If you want a flashy deal of $12.50 per sensor, go for them. Each unit they sell contains FOUR sensors, and they will now have four more for sale.
