      Always the highest quality parts from Optima. Honest quotes with transparent lead times. They stand behind their work and are reliable. Fastest shipping and excellent customer service. They machine parts to tolerances that nobody else can or will do. Jan's my go-to machinist when the precision matters.

      Optima Precision produced quality prototype parts with a great tolerances and surface finish on a short lead time. Couldn't ask for anything more.

      I met Jan of Optima Precision through my roommate at the time who is a builder of rockets and aerospace vehicles by trade. He had been working to with Optima Precision to machine high precision turbopump components for his rocket and was pleased with the quality and consistency of the workmanship.

      I work as a mechanical engineer at Tesla Motors and frequently require prototype motor parts machined. After being introduced to Jan I asked him to quote me some parts and found the quotes to be very competitive on price and lead time. I even received some parts in under 24 hours. The attention to detail is always there.
