Satisfied Customer.
I made my first purchase from Propel Parts last week. I was very happy with the response time and the delivery was fast, fast, fast! Also, the quality of the product is superb and at a great low price.
Keep up the great work! -
Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you. -
Great service at an affordable price to get my machine back going.
