Great product. The crystals in my black rims look so good. Don't know why I didn't buy that one long time ago even though I always bought the rings for the inside of car or door handle. As you can see in photo and I circled it where it's at. Also I provided video that another reviewer had on her video that doggone it she is right. Had to see for myself and if it effects multiple cars different types and yes it does. I have a 2011 Mazda CX 7 NO push to start but I had a ring on my ignition key part before but on a 1998 Honda Accord so maybe since it was older it didn't mess up but having it on there after I put it on drove off. Parked at a store did my shopping came out and it didn't start lol it got to it somehow. So I guess if you have a newer car and it isn't push to start than it will make your computer in your car read that there's sumthin wrong idk why just from the ring. But either way didn't start. And luckily I just popped it off and it immediately started back up. Only can provide one video and very short per review. So only showing when it didn't work wanted to show that I took it off and it immediately worked but won't all fit.
