Customer Reviews
Fast communication, and very Helpful!
Great Customer Service!
Had some difficulties with the website. Contacted customer service. Once I communicated the issues I was having Steven worked through getting my order processed and making sure I got my receipt and all issues resolved. Perfect!
Great prices prompt courteous customer service and fast shipping.
I’ve been ordering parts from propel for about 3 years & counting. I live in Hawaii where we have a hard time getting parts especially for decent prices with fast shipping. I've been 100% satisfied with the company and the customer service and will continue to use them. I recommend propel to everyone here in Hawaii and we are all happy to have you guys. Thank you!!!
Stevens the man. Placed my order and sent him the order # and had me in the loop within an hour.
He was a great help with ordering and refunding the sales tax,
