Great communication with emails and quick delivery. I was worried about not getting the right parts bc the discontinued parts were hard to find and their site showed inexpensive pricing. But they are legit! Def 5 stars. Thanks!!! The part in my hand is my existing broken Volvo dashboard rings. Bought 2 from the store shown in the white packages... bc... ya know... just in case 😎
