Car dealerships prefer well-known brands, and some refused to put them on me. I literally had to pay the store to install these stems but they couldn't program them. I don't know if the tech at the shop was incompetent or if they were, but everyone there said "off-brand" TPMS sensors will hurt you. Now I got them working after buying my own Autel TPMS programmer ($270) but even that was a problem and I had to use another tool to insert the IDs into my Jeep computer. SO. $340 later; I have a working system. BUT. Now it says it can't tell if the rear sensors are upside down and throws a tire code error. I give up.
