I ordered several sets of these. Be very cautious with these. I do not know if one of the sets I received was defective or if they are all the same but after installing these in my friends vehicle and using them on a long trip from home, my friend and I both ended up with broken phones. My screen was cracked to the point my phone could no longer be used and it just barely damaged my friends phone. I would be very cautious using these because we did have that bad experience with them but like I said, it could have been just the one defective set. The seller did make things partially right with me and pay what it would have costed me to replace my phone screen (although I had to purchase a new phone I could not go without a phone for weeks) after I did complain. So the seller is fair also.
