My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
All looks very nice. [I chose E.I. because of] previous experience.
