Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Very impressed with the clarity and readability of the CGR-30P gauge.
Great Service.
Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
Great product. [I chose EI because] you have no competition.
My mechanic said that your product was very good, and he was correct.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
The tach looks and operates amazing. Extremely accurate.
The CGR-30P is a fantastic product and EI has excellent customer service. EI is the leader in engine monitors with a strong track record.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
Your customer service is excellent and your products are top quality!
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
