“I have NO complaints about Sunstone’s boards and services are ALWAYS of HIGHEST QUALITY & ON TIME DELIVERY!! I design and manufacture systems and boards for 3 different companies. At this point Sunstone Circuits is doing all our prototype and production boards! I run Primrose Technology and ReflexiveTech, Inc., and have not found a better board shop!”  
– Paul Primrose, Primrose Technology


“Thanks for the e-mail. You are the best and Im loving our experience with Sunstone so far - smooth ordering, responsive staff, discounts and shipping a day early. I could not be happier and just wanted to express that to you directly!! Hopefully I got the design right this time and we can place a production quantity order in the near future. Thanks again!!” 
–Jamie C, Customer


“I’ve been actively using Sunstone since 2006. I’ve come to appreciate greatly the consistency of a high level of performance against promise delivery dates, quality product, competitive pricing and a very strong customer support group. Any questions or issues with fab data files are raised quickly and resolved real time. Since many of my designs are time critical to meet proof of concept or sales samples, its critical to have a supplier that can be counted on. And this is why after 7 years I’m still a “Sunstone” guy. Thank you Sunstone and looking forward to the next board engagement.” 
– Greg Martocello, Rochester NY
