Hi guys, I got those from automotive concepts they cost me 175$ and two small rings broke during the transporation, two big ones broke after two days!!! They are very fragile and it look they would brake easily if the temperature changes! So I got different ones on Ebay, 70$ much different aluminum backing, silicon wires, serrated lines and 3 pin connectors. They are not that thin but they work great and I hope they will continue! Cheers! ;)
PS- this is the website where u can find them! ;)
