The two holes on the muffler side were rusted on my 4 yo 2017 RAV4. As fafr as Ugg are concerned, I think anyone would find it extremely difficult to beat their quality. I did not try the wired mode since the whole reason I purchased these was to use wireless. My only criticism is that they are not magic transforming pjs, and I will still have to hold on to a few pair of fleece jammies for the few chilly months we do get in Arizona. I have the tower tied up against a house post. Also, 100% cotton! Im so glad I got him these. But, since its in my hall and no one is looking at the paint job I decided to build it and then make a decision. Some people said it was flimsy, shaky, not that thick of steel, hard to put together. I have a red Mercedes and this key chain works perfectly with my remote.
