I bought these in November 2020 on Black Friday, installed them next weekend and the sensors won't fire or train on my 2013 Honda Civic and spend $100 on sensors and money. Installation spent 200 on sensors with installation and not even working great. I asked the seller to replace or refund the money as I don't need it. I didn't even reply, spoke to a Revain support rep who said to delete them and refund the money, so now I have to spend another $100 to get my $100 back? It makes sense to stay away from these sensors and I'm not the type to write reviews but this one is unacceptable!
