Overall I am very happy with my experience. Items all shipped out quickly. I paid for second day air and the items shipped out the same day. My only complaint would be they shipped from Three different locations and I received them three different days. They shipped Fedex and the parts came Friday, Saturday, and Sunday. I was not really upset because I did call and was told they might not ship the same day and so I was expecting them Monday. Overall very happy.

quick

So far all is ok
