Review on Otostar Crystal Headrest Collars Interior Interior Accessories by Patrick Johnson

Nice to look at, nice to hold and then it hits. The only way to use them is to have the headrest disassembled or removed by a $$$ qualified mechanic. These rings are just rings. There is no way to open them and place them as shown in the ad. They are strong, well constructed "rings". If you have an older model car where the headrest/rests can be removed easily and simply with the push of a button then you are in luck otherwise the rings will not be able to be used for their intended purpose. I would like to suggest that Revane clarify this. My advice is not to buy this version.
