“I own a small LED lighting company with an emphasis on small. When I was starting out I could not find anyone interested in doing layout and assembly work for small batches of boards on a job by job basis. After being turned down by the 4th or 5th large board designer that was only interested in my potential volume I finally asked for a recommendation. I was given three names and RJS Electronics was one of them. I did a little research, read all the recommendations on the RJS website and decided to give them a call. John worked with me on my layout and design, made suggestions where necessary and put together a proposal. I like the honest up front pricing, flexibility and his ability to deliver per the agreed delivery date. I have used RJS Electronics for several board iterations and will continue to use them for all my electronics needs. ”
