I would have to put a lot of the blame on Crower also. If a customer, or say even just a friend, sent me a piece of equipment that needed a part built into it and wanted me to build it and install it. I would think that when designing the product I should take into consideration what this product is going to do and be used for and would not give it back without making sure it is right. As I would suspect that the customer or friend would also expect it to be right when they got it back so they could go back to work without have to REcheck my work
