Excellent Customer service
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!!!
