I would have hoped with such an expensive device and subscription model that the customer service would be better than it is. I had a couple of questions on my two devices that normally I could have self-served by logging onto my account online. Unfortunately all my history was not available so I had to contact Road Angel for support. I am still waiting for a response a week later. As for the devices themselves, I have two issues, the first is about reliability, I have had to repair/replace bit of my devices a year or so after the warranty had expired and the second is that I have noticed that the prevailing speed limit in a particular area is not accurate, which means neither would be the alerts. (Today I drove though Surbiton and Kingston which is a 20MPH area, my Road Angel reported most of the time that I was in a 30 MPH zone. (Interestingly my BMW and Waze reported the speed limit correctly) Having said all of the above I have had Road Angels since they were first launched and have saved me from fines numerous times. If the reliability, accuracy and service levels don't improve however, I am not 100% sure I will renew the subscriptions when the expire next year.
