    Very prompt shipping - received it the next day, even though the product page showed slower shipping. The product shipped did not match what was listed in the product page. So, reached out to the seller, and received a prompt response. The seller was very polite, and requested me to ship the item back (through FREE shipping) and for a FULL REFUND. I'll use this seller again.

    Hello. Received this in a box where it was supposed to have two hoses. The 549, and the 547. This would have allowed me to change the hoses in the mustang. Unfortunately who ever picked the order didn’t put both hoses in the box. This vendor was emailed multiple times. Unfortunately they never responded. So here I am writing this stupid message . My thought was buy from the same vendor so shipping would have been easier. But now I’m out $62 bucks for a hose.,and they loose the future sales.

    Received the part in a timely manner. From ordering to processing to shipping to receiving was very quick. This part looked new as advertised. A good quality part for the price that was packaged in bubble wrap and a box. It was clean and fit my 2001 Honda Accord EX perfectly. More importantly, it worked as advertised. Would buy from this seller again!
