I consider myself pretty handy, but I was lost on this one. My garage door spring broke, and I couldn't find my size. I ordered the closest one to my size and put a note in my order. They immediately got in touch with me and got to work. MJ walked me through what I needed. Told me my spring size was abnormal. MJ had me text him pictures. He talked to the company engineer. Made sure I only needed the one spring instead of two. But guess what, they didn't sell the size I needed. He said he would talk to a company they worked with and have it custom made, or I could continue to look for the size I needed. I saw dollar signs and said I would look for it somewhere else. Guess what, couldnt find it. I called MJ, and asked him to see about the custom order. He called me back. Yup, they could do it. And guess what? No extra cost! The spring was a great deal, and was well made. Everything extra I needed to install my spring was included. I bought cables too. They were double as thick as the original cables. If i could give this company a higher rating, I would. Awesome product. Unbelievable customer service.
