Robert ,BMW 320D

Excellent customer service with knowledgable staff.

J.S.,Jeep Cherokee 3.0 V6

Although these are early days I have already been agreeably surprised by the significant improvement in fuel economy registered by the car's onboard computer. Although this was never really a priority in purchasing the device it is certainly a welcome bonus.

I am a very satisfied customer and glad to have been able to find a device which my insurance firm were able to readily accept without increasing my premium too ridiculously, a device which is British instead of German or American, and a device which seems to perform as claimed.
