Customer Service is Awesome

Called with a concern over a gasket I had ordered and when it arrived it didn’t look correct. Spoke to customer service, sent some pics and they followed up with their supplier and got back to me the same day. That is what I consider superior customer service – and this was just for a $10 gasket – I will be using them for all my future orders!

Awesome job all the way across the board, from the initial answer of the phone to the product search to the timeliness of the shipping and ending with the ease of returning the core for a credit. I couldn’t be happier!
