We have had several projects in the area of biomedical diagnostics with EFJ Engineering in the last few years. It was a pleasure to work with them on prototype design and their expertise in design, advice and guidance on manufacture is superb.  The work was produced in a timely manner and the quality of the work was excellent. We look forward to working with this company in the future.

Having worked with EFJ Engineering for over 4 years we have found them to be extremely professional, flexible and efficient. They provide a high-quality service and they're flexibility in meeting very short lead times has proven to be to very beneficial to us on a number of occasions.

We are a young startup with an academic background at Dublin City University. When we needed to scale up and produce microfluidic devices within certain ISO standards, EFJ Engineering was the place to go. We found the team very passionate and extremely engaging to work with and they were very generous when several prototypes had to be developed before the final design for manufacturing was completed. We plan to work closely with EFJ in the future and I would recommend their services to anyone.

We are a team of academic researchers working on a multidisciplinary project. When we needed to scale up production of our customized microfluidic flow chamber EFJ Engineering were our first port of call. Their expertise and advice has been instrumental in guiding improvements in the design of our device. The team take a genuine interest in our projects, helping to troubleshoot when designs have had to be changed. Over the years we have worked together on a number of different microfluidic based projects. They consistently provide an excellent service and we have no hesitation in recommending them to anyone.
