they answered my emails in a few business days. you can definately trust them. They SHIP QUICK. as in i got my order a week after i ordered them straight from japan. they are legit and awesome to deal with (even if it takes a few days to get a reply). they are courteous and will make every effort to help you. hell, it sometimes takes me longer to get replies from some vendors here in the US than it does from japanparts.com.
